Come...let us walk - Here Isaiah is speaking to those who have ears to hear in his own day. Come is not just a suggestion but a command which is followed by an exhortation (let us walk). The idea is now that you've heard about the behavior of the foreign nations in the future, let this motivate you to follow their example even now (in Isaiah's day).

House of Jacob - 22v in Scripture (9 uses by Isaiah) - Ge 46:27; Ex 19:3; Ps. 114:1; Isa. 2:5, 6; 8:17; 10:20; 14:1; 29:22; 46:3; 48:1; 58:1; Jer. 2:4; 5:20; Ezek. 20:5; Amos 3:13; 9:8; Obad 1:17, 18; Mic. 2:7; 3:9; Lk. 1:33

John Martin makes the excellent point that...

When great truths about the future are given in the Scriptures, readers are often reminded of how they should live in the present (e.g., 1Th 4:13, 14, 15, 16, 17, 18-note; 1Th 5:1, 2, 3, 4, 5, 6, 7, 8-note; 2Pe 3:10, 11, 12, 13, 14-note; 1Jn 3:2, 3). In view of the fact that in the Millennium all nations will stream to Jerusalem to learn God’s Word, it would be sensible for Israel, already knowing that Law, to follow it (walking in its ”light“) until the Lord sets up His glorious kingdom. (Walvoord, J. F., Zuck, R. B., et al: The Bible Knowledge Commentary. 1985. Victor or Logos)

MacDonald suggests that...

The glorious prospect of Christ’s kingdom moves Isaiah to call the people of Judah to repentance immediately. (MacDonald, W & Farstad, A. Believer's Bible Commentary: Thomas Nelson or Logos)

Grogan has an interesting thought writing that...

Isaiah viewed the future obedience of the nations to the true God as a challenge to the house of Jacob to walk in his ways. The nations are not yet coming to Jerusalem to be taught by the Lord, but Israel already has his word. How unthinkable then that she should continue to walk in darkness! The Christian is faced by the same kind of challenge in Ephesians 5:8-20 (see notes). (Grogan, G. Isaiah: Expositor's Bible Commentary 6-Volume New Testament. Zondervan Publishing)

Walk in the light of the LORD - (contrast Is 59:9, 10) Light exposes, reveals or uncovers that which is not seen because of darkness. In the immediate context, Isaiah has just shed a brilliant prophetic light on Israel's future glory. The upshot is that this sure hope of future grace and glory should serve to motivate a walk commensurate with that truth. Specifically what manner of walk is he calling for? Although it is not stated, comparison with numerous other texts leaves no doubt that God through His prophet Isaiah is exhorting his Jewish readers to a worthy walk, a walk of holiness (cp the effect of "hope" in 1Jn 3:2, 3). As stated many times on this website, what you are looking for will (or should) affect what you are living for.

A true knowledge of the future should always impact our behavior in the present. Otherwise we have become hypocrites -- "smarter sinners", "modern day Pharisees" who will be held accountable for our greater revelation.

Smith writes that the response of his Jewish hearers...

will determine whether Isaiah's audience will enjoy the kingdom God prepared for those who follow Him, or miss out on this great privilege. That same choice is required of all people since the time of Isaiah. People in every generation must choose to come to God, learn of His ways, and enjoy His kingdom, or they can proudly focus on their own accomplishments, close their ears and eyes to what God says, and suffer a humiliation similar to what Isaiah prophesies (Is 2:6-22). (New American Commentary - New American Commentary – Volume 15a: Isaiah 1-39.)

The psalmist says we are to walk not just in any light but in the light of a Person...

Psalm 89:15 How blessed are the people who know the joyful sound! O LORD, they walk in the light of Thy countenance (of Your face).

Augustus Montague Toplady comments that...

Surely, next to the love of God's heart, believers value the smiles of his face; from which, as from the agency of the sun, arise the budding of conscious joy, the leaves of unsullied profession, the variegated blossom of holy tempers, and the beneficent fruits of moral righteousness. They are totally mistaken who suppose that the light of God's countenance, and the privileges of the gospel, and the comforts of the Spirit, conduce to make us indolent and inactive in the way of duty. The text cuts up this surmise by the roots. For, it does not say, they shall sit down in the light of thy countenance; or, they shall lie down in the light of thy countenance; but "they shall WALK in the light of thy countenance." What is walking? It is a progressive motion from one point of space to another. And what is that holy walking which God's Spirit enables all his people to observe? It is a continued, progressive motion from sin to holiness; from all that is evil, to every good word and work. And the self same "light of God's countenance" in which you, O believer, are enabled to walk, and which at first gave you spiritual feet wherewith to walk, will keep you in a walking and in a working state, to the end of your warfare.

In Ephesians Paul writes to the predominantly Gentile believers...

 you were formerly darkness, but now you are light in the Lord; walk (present imperative = command to make this your practice to walk in a manner which pleases the Lord) as children of light (Ep 5:8-note)

In Romans Paul admonishes the believers at Rome that...

The night is almost gone, and the day is at hand. Let us therefore lay aside the deeds of darkness and put on the armor of light. Let us behave properly as in the day, not in carousing and drunkenness, not in sexual promiscuity and sensuality, not in strife and jealousy. But put on (aorist imperative = Command to do this immediately and effectively! Speaks of urgency. Soldiers put their gear on before battle lest they become seriously injured!) the Lord Jesus Christ, and make (present imperative + negative = stop making plans to sin!) no provision for the flesh in regard to its lusts. (Ro 13:12-note, Ro 13:13, 14-note)

Isaiah later speaks of walking rightly declaring that...

He who walks righteously (then he enumerates what a righteous walk looks like), and speaks with sincerity, He who rejects unjust gain, And shakes his hands so that they hold no bribe; He who stops his ears from hearing about bloodshed, And shuts his eyes from looking upon evil; He will dwell on the heights; His refuge will be the impregnable rock; His bread will be given him; His water will be sure. Your eyes will see the King in His beauty (Christ Jesus, the King of kings); They will behold a far-distant land. (Is 33:15, 16, 17)

And a highway will be there, a roadway, and it will be called the Highway of Holiness. The unclean will not travel on it, but it will be for him who walks that way, and fools will not wander on it. No lion will be there, nor will any vicious beast go up on it. These will not be found there. But the redeemed will walk there, and the ransomed of the LORD will return, and come with joyful shouting to Zion, with everlasting joy upon their heads. They will find gladness and joy, and sorrow and sighing will flee away. (Is 35:8, 9, 10)

Yet those who wait for the LORD Will gain new strength; They will mount up with wings like eagles, They will run and not get tired, They will walk and not become weary. (Is 40:31)

"When you pass through the waters, I will be with you; and through the rivers, they will not overflow you. When you walk through the fire, you will not be scorched, nor will the flame burn you. (Is 43:2)

Later in Isaiah God explains how not to walk declaring...

In Isaiah 2:6-9 we see Judah and Jerusalem "full" but empty and in Is 2:10-19 we see the proud high but made low! God is never mocked.

Isaiah moves from glory back to gloom beginning in Isa 2:6 and continuing through Isa 4:1, these passages including Isaiah's exposition of the terrifying Day of the LORD (Day of Yahweh).

You - Isaiah is now addressing God directly.

You have abandoned Your people - He is speaking of Judah and Jerusalem whose pride precluded reception of God's presence and blessing.

Abandoned (05203) (natash/natas) is used in 39 verses (twice in Ezek 31:12) in the OT and about 50% of the uses convey the idea to forsake, reject leave alone. The idea is to cause a relationship or association to cease until there is the possibility of renewal.

Natash - 39v in the NAS - Gen. 31:28; Exod. 23:11; Num. 11:31; Deut. 32:15; Jdg. 6:13; 15:9; 1 Sam. 4:2; 10:2; 12:22; 17:20, 22, 28; 30:16; 2 Sam. 5:18, 22; 1 Ki. 8:57; 2 Ki. 21:14; Neh. 10:31; Ps. 27:9; 78:60; 94:14; Prov. 1:8; 6:20; 17:14; Isa. 2:6; 16:8; 21:15; 32:14; 33:23; Jer. 7:29; 12:7; 15:6; 23:33, 39; Ezek. 29:5; 31:12; 32:4; Hos. 12:14; Amos 5:2.

The NAS renders natash as abandon(7), abandoned(5), allow(1), cast away(1), ceased(1), drawn(1), fall(1), forego(1), forsake(3), forsaken(2), forsook(1), hangs slack(1), leave(2), left(5), lie fallow(1), neglected(1), spread(6).

The TWOT notes that...

Often natas is used of God forsaking or casting off his people (Jdg 6:13; 1Sa 12:22; 1Ki 8:57; 2Ki 21:14; Ps 94:14; Isa 2:6; Jer 7:29; 12:7; 23:33, 39). On the other hand, God (Dt 32:15; Je 15:6), David (Ps 27:9) or Egypt (Ezek 29:5) may be the object of natas. The term is also used of forsaking the tabernacle at Shiloh (Ps 78:60) and of rejecting the teaching of one’s mother (Pr 1:8, 6:20). (Harris, R L, Archer, G L & Waltke, B K Theological Wordbook of the Old Testament. Moody Press or  Logos software version) 

For example, in the book of Judges (see the "theme" Jdg 21:25-note) Israel repeatedly forgot and forsook the living God to chase after the deceptive dross and dregs of vain idols. And so we read...

Then Gideon said to Him (the Angel of the LORD), "O my lord (Appropriately a "little l, rather than a capital "L", for it appears Gideon had not yet had his eyes opened to understand with Whom he was speaking! May our eyes be opened by the Spirit to hear the Lord's voice in His Word!), if the LORD is with us, why then has all this happened to us? And where are all His miracles which our fathers told us about, saying, 'Did not the LORD bring us up from Egypt?' But now the LORD has abandoned (natash) us and given us into the hand of Midian."

Why Will God
Judge His People?

Because - Always be alert to this and similar connective conjunctions such as "since", "for" (not always explanatory - check the context) and ask "Why?" (see interrogate with the 5W'S & H). These conjunctions explain the reason for what precedes, in this case the reason for God's abandonment. The Holy One of Israel is not capricious, but gives clear reasons for abandoning His people. In fact this entire next section from Isa 2:6 through Isa 4:1 deals with God's "reason" for forsaking His chosen people.

They - Notice that in Is 2:5 Isaiah includes himself in the exhortation to a worthy walk, but in this section of "indictments" against Judah and Jerusalem he does not include himself but instead uses pronouns they...their...them.

In this next section extending from Isa 2:6 through Isa 4:1 (Isa 4:1 is a "poor chapter break" and would have been more appropriate in chapter 3) after outlining Israel's future hope in the Messianic age to come and calling for a walk concordant with that sure hope, Isaiah returns to review God's righteous indignation against Judah because of her greed, idolatry and haughty spirit.

Filled with influences from the east - (see filled with idols below in Is 2:8) What a contrast with the previous section where "many peoples (Gentiles) will come" to Jerusalem to learn of God. Here many Jews were pursuing spirituality and had become filled with the ways of the world's religions, especially the Eastern religions!

Warren Wiersbe notes that...

The growth of Eastern religions in the modern Western world is a phenomenon that is both frightening and challenging. Even nonreligious people are practicing Eastern forms of meditation and relaxation, following techniques that are being taught in university classes and business seminars. (Wiersbe, W. W. Be Comforted. An Old Testament study. Wheaton, Ill.: Victor Books)

Filled with - Dear reader, you can mark down the maxim that whatever you allow to "fill" you will eventually control you. If you are filled with anger, rage or jealousy, these emotions will control you. If you are filled with the Spirit, He will control you (Ep 5:18-note, compare Col 3:16-note for a practical way to "be continually filled"). If you are filled with eastern teachings (New Age, eastern mysticism, etc), be aware that these influences are not neutral but will exert control on your mind and subsequently on your thoughts, words and deeds. There is a subtle but growing influence infiltrating the the modern evangelical church and it is characterized by the pursuit of "mystical" experiences (eg, mystical practices in prayer, etc). The closer the day of Christ's return, the more subtle will be the counterfeit religious practices! In order to be a worthy Berean (Ac 17:11-note) fortify yourself daily with the Word of Truth (Mt 4:4, Jn 17:17, 1Pe 2:2-note) so that you will be enabled by the Spirit to discern truth from error in these "last" of the last days (He 5:14-note, 1Th 5:21, 22-note), cp Col 2:8-note)

The tragedy (among many) is that according to Isa 49:6 Israel (Judah) was to have been "a light among the nations (Gentiles)" so that God's "salvation may reach to the end of the earth" (God's commission to the nation, which Paul took seriously and carried out as he said in Acts 13:47). As a result of their defilement, the chosen people instead of being light and salt to the nations, had lost their savor and had "become tasteless...good for nothing anymore, except to be thrown out and trampled under foot by men." (Mt 5:13-note). Beloved, lest we are too hard on Judah, we need to examine the saltiness of our salt and the clarity of our light before lost men and women (both Jews and Gentiles) whom God has placed in our path. (Mt 5:14, 15, 16-note)

Chuck Smith writes that in Is 2:6, 7, 8 gives us...

An apt description of present-day humanism. Man worships the creature rather than the Creator.

And they are soothsayers like the Philistines: (Is 8:19; 47:12,13; Exodus 22:18; Leviticus 19:31; 20:6; Deut 18:10, 11, 12, 13, 14; 1Chronicles 10:13)

Soothsayer - a seer or one who is supposed to be able to predict the future by various means. One thinks of the modern fascination with Nostradamus (in Jan, 2009 there were over 7 million hits for the search term Nostradamus! This compares with some 17 million for Messiah.) The American Heritage Dictionary defines "sooth" as truth (or real, reality) and thus the idea is one who claims to speak the truth. Thus in a real sense a soothsayer is essentially a false prophet.

The 1828 Webster's dictionary defines soothsayer as...

A foreteller; a prognosticator; one who undertakes to foretell future events without inspiration.

Whom should have Judah consulted? Obviously the omniscient One and yet they exchanged this lofty privileged access for lowly pagan inquiry.

Like the Philistines (cp 1Sa 6:2; 2Ki 1:2) - God's holy people were resorting to the unholy practices of the pagans. This is ever the danger for God's people in this fallen, seductive world. Have you been ensnared by pagan practices and/or practitioners like Nostradamus who appeal to that part in all of us which wants to know the future? If you want to know the real truth about the future, then seek the true Prophet (Jesus Christ - predicted in Dt 18:15, 18), and God's Plan for the Ages in the Bible (see Bible Prophecy and God's Plan for the Ages according to the Bible)

The contemporary prophet Micah has a similar prophecy in which God Himself declares...

I will cut off sorceries from your hand, And you will have fortunetellers no more. (Mic 5:12)

The chosen people repeatedly refused to choose the only God and instead chose those who were no gods. They stubbornly refused to acknowledge in their heart that God is (justifiably) a jealous God (Ex 20:5, 34:14, Dt 4:24, 5:9, 6:15, Josh 24:19) Who tolerates no rivals. Their continual refusal to acknowledge His Lordship in their life, led them to repeatedly incurring the righteous wrath of God God's wrath is not purely vindictive or retributive but ultimately seeks to destroy all idols and foolish religious practices so that His people will recognize Him as the only God. Dear believer, beloved by the Most High God, are there any idols you are hiding in the closet of your heart? I implore you...

Do not be deceived (present imperative + a negative = Stop being led astray, stop being seduced by the vain, empty idols of this present evil world system, Gal 1:4) , God is not mocked (e.g., beware of Israel's bad example - SLOWLY READ AND PONDER 2Chr 36:15, 16, cp Pr 1:30); for whatever a man sows, this he will also reap (Ho 8:7 contrasted with Ho 10:12). For the one who sows to his own flesh shall from the flesh reap corruption, but the one who sows to the Spirit shall from the Spirit (Jn 6:63) reap eternal life. (Gal 6:7, 8, cp He 3:13-note)

Sow a thought, reap an action.
Sow an action, reap a habit.
Sow a habit, reap a character.
Sow a character, reap a destiny.

and they strike bargains with the children of foreigners: (Exodus 34:16; Numbers 25:1,2; Deuteronomy 21:11, 12, 13; 1Kings 11:1,2; Nehemiah 13:23; Psalms 106:35; Jeremiah 10:2)

Entanglement by the Cords of one's own Sin - Not long after a wealthy contractor had finished building the Tombs prison in New York, he was found guilty of forgery and sentenced to several years in the prison he had built! As he was escorted into a cell of his own making, the contractor said, “I never dreamed when I built this prison that I would be an inmate one day.” (cp Nu 32:23)

Filled with silver and gold...no end to their treasures - Judah instead of placing their hope in the Holy One, chose to trust their accumulation of wealth in the form of precious metals and a plethora of possessions. This love of the world's treasures instead of God is as much idolatry as any carved image. In some ways, this misplaced love of money and things is worse than wooden and stone carvings, for it deceives one into justifying that after all I'm not a pagan idol worshiper!" This genre of thinking permeates the insidious idolatry that has permeated American culture in the twenty-first century.

If we fill ourselves with anything other than God, the result is emptiness and abasement.

Filled (04390 )(male) can have a spatial sense (which is the case in this verse), as when the locusts filled the houses of the Egyptians (Ex 10:6) or the wine press (cp Re 14:19, 20, 19:15) being filled (figuratively speaking of wickedness) (Joel 3:13).\

Filled (male) is translated in the Septuagint (LXX) with the verb empiplemi (this Greek verb also used in Is 2:6, 7, 8, 9:19; 11:3, 9; 13:21; 14:21; 21:3; 22:2; 23:18; 27:6; 29:19; 31:4; 33:5; 34:6, 7; 44:16; 58:10, 11; 65:20; 66:11) which means to completely take up the space of something or to provide a sufficient amount (to satisfy - something idols can NEVER do!) See above for discussion of what fills someone will control them!

Their land has also been filled with horses and there is no end to their chariots: (Is 30:16; 31:1; Dt 17:16; 1Ki 4:26; 10:26; Ps 20:7; Ho 14:3)

Wiersbe comments that...

The prosperity of the nation made the leaders proud and covetous. Instead of trusting the Lord, they trusted their wealth and war equipment, not realizing that neither would deliver them in the coming day of judgment. (Ibid)

David admonishes and encourages us with his example writing...

Some boast (trust = KJV) in chariots, and some in horses; but we will boast in the Name of the LORD, our God (see the study - Name of the LORD is a Strong Tower). (Ps 20:7)

Spurgeon comments:

Chariots and horses make an imposing show, and with their rattling, and dust, and fine caparisons, make so great a figure that vain man is much taken with them; yet the discerning eye of faith sees more in an invisible God than in all these. The most dreaded war engine of David's day was the war chariot, armed with scythes, which mowed down men like grass: this was the boast and glory of the neighbouring nations; but the saints considered the name of Jehovah to be a far better defence. As the Israelites might not keep horses, it was natural for them to regard the enemy's calvary with more than usual dread. It is, therefore, all the greater evidence of faith that the bold songster can here disdain even the horse of Egypt in comparison with the Lord of hosts. Alas, how many in our day who profess to be the Lord's are as abjectly dependent upon their fellow men or upon an arm of flesh in some shape or other, as if they had never known the name of Jehovah at all. Jesus, be thou alone our rock and refuge, and never may we mar the simplicity of our faith.

We will remember the name of the Lord our God. "Our God" in covenant, who has chosen us and whom we have chosen; this God is our God. The name of our God is JEHOVAH, and this should never be forgotten; the self existent, independent, immutable, ever present, all filling I AM. Let us adore that matchless name, and never dishonour it by distrust or creature confidence. Reader, you must know it before you can remember it. May the blessed Spirit reveal it graciously to your soul!

William Plumer...

Vain is the confidence of all wickedness. In war, chariots, horses, navies, numbers, discipline, former successes, are relied on; but the battle is not to the strong. "Providence favours the strong battalions" may sound well in a worldling's ear, but neither Providence nor the Bible so teaches. If peace, riches, friends, ships, farms, stocks, are relied upon, yet they can neither help nor save. Let him who glories, glory in the Lord.

Their land - Judah and Jerusalem. Jotham and Ahaz, two of the kings under whom Isaiah prophesied, failed to remove the idolatrous high places from the Land (2Ki 15:35; 16:4).

Filled (04390 )(male) can have a spatial sense (which is the case in this verse), as when the locusts filled the houses of the Egyptians (Ex 10:6) or the wine press (cp Re 14:19, 20, 19:15) being filled (figuratively speaking of wickedness) (Joel 3:13).

The Septuagint (LXX) uses the verb empiplemi (also used by the Lxx in Is 2:6, 7, 8, 9:19; 11:3, 9; 13:21; 14:21; 21:3; 22:2; 23:18; 27:6; 29:19; 31:4; 33:5; 34:6, 7; 44:16; 58:10, 11; 65:20; 66:11)  which means to completely take up the space of something or to provide a sufficient amount (to satisfy - something idols can NEVER do!) See above for discussion of what fills someone will control them!

ABOMINABLE,
DETESTABLE
IDOLS

Filled with idols - This is the first use of the word idols in Isaiah. It was not just that Judah and Jerusalem just had idols or practiced idolatry, but that they were "filled to the brim" with abominable lifeless idols! It is interesting that in a survey of the OT prophets, idols and idolatry per se are not a common theme (except in Ezekiel, Hosea, Isa 40-55), the other prophets being more concerned with the moral offenses of God's people. In Is 2:6-22, the primary focus of the "attack" is pride

Related Resources: Greek Word studies on - Idols = eidolon; Idolater = eidololatres;  Idolatry = eidololatreia

Idols (0457) (eliyl/elil [plural = elilim]) (Used in Is 2:8, 18, 20; 10:10, 11; 19:1, 3; 31:7) describes that which is worthless, good for nothing, of no value (cp powerlessness). The spelling of the Hebrew word for idol is very close to the Hebrew word for God (= el) (and some etymologists suggest it is actually a diminutive of the Hebrew word for God). The term for God however relates to the idea of strength or power, which makes Isaiah's contrast with "nothing" (eliyl) all that more pointed and dramatic! Worthless and good for nothing is a fitting name for objects of worship made by human hands! God's assessment of any "god" but Himself  is that  “all gods of the peoples are nought (nothing)” (Ps 96:5YLT = 1Chr 16:26YLT)

Eliyl - 18v in the OT - Lev. 19:4; 26:1; 1 Chr. 16:26; Job 13:4; Ps. 96:5; 97:7; Is 2:8, 18, 20; 10:10, 11; 19:1, 3; 31:7; Jer. 14:14; Ezek. 30:13; Hab. 2:18; Zech. 11:17

Habakkuk has a classic parody of idols asking...

What profit is the idol when its maker has carved it, or an image (KJV = molten image), a teacher of falsehood (lies)? For its maker trusts in his own handiwork when he fashions speechless idols (elilim). 19 "Woe to him who says to a piece of wood, 'Awake!' To a dumb stone, 'Arise!' And that is your teacher? Behold, it is overlaid with gold and silver, And there is no breath at all inside it. 20 "But the LORD is in His holy temple. Let all the earth be silent before Him." (Hab 2:18, 19, 20)

Comment: Observe the contrast of lifeless idols with the living LORD, and those who call the idols to "Awake...arise" are told to be silent before the Lord.

The following is a Biblical summary of eliyl - They are the product of human hands (Is 2:8, 20; 31:7; Lv 26:1), and one can therefore discard them (Is 31:7); they are dumb (Hab 2:18); they quiver before Yahweh (Is 19:1) and vanish before Him (Is 2:18). The expression eliyl recalls the impotence and the insignificance of these strange gods. The force of the term is probably most clearly seen in Ps 96:5YLT “for all gods of the peoples are nothing, but Yahweh made the heavens.”

Elilim often parallels other words related to idols - pesel/pāsîl “sculpted image” (Is 10:10; Lv 26:1; Hab 2:18; Ps 97:7),  'atsab “carved image” (Isa 10:11), gilluwl “idols” (Ezek 30:13), and massēkâh “molten image” (Lv 19:4; Hab 2:18).

Eissfeldt (TLOTOT) summarizes the OT designations for “idol” into five groups according to the OT Scriptures...

(1) Derogatory terms: bōšet “shame” (bos = to be ashamed), šiqqûs “horrible thing,” tôebâ “abomination” (tb = abhor), hattat "sin” (ht' = to miss a mark, fall short), 'ēmâ “horror”;

(2) Terms that deny the existence of the gods represented by the idols: hebel “vapor, breath,” šeqer “lie” (šqr = to deceive),  šāw “vanity, deceit” elîl “nothing,” lō-ēl (no god) and lō-elōhîm “not-god”

(3) Terms that deny idols divine dignity and relegate them to the sphere of the lower, evil spirits: śeîrîm “satyrs,” šēdîm “demons,” → āwen “harm, disaster, evil power”;

(4) Designations that declare them to be foreign and so more or less explicitly describe them as useless: phrases with ahēr “other”,  zār “foreign, strange, different” (verbal adjective of the root of zur = to turn away), nēkār “strange, foreign” → hādāš “new”;

(5) Designations that identify them with their images and so declare them to be lifeless matter: massēkâ and nesek “molten image,” pesel and pāsîl “sculpted image,” ōseb and āsāb “carved image,” → selem and semel “carved image,” gillûlîm “(hewn) blocks of stone,” sîr “image,” maśkît “showpiece,” and neśûâ “processional image.”

The Septuagint (LXX) renders elilim variously, most frequently with cheiropoiēta “human product” (6x) and eidola “idols” (4x).

Paul describes the vanity of idols writing to the Corinthians that...

concerning the eating of things sacrificed to idols, we know that there is no such thing as an idol in the world, and that there is no God but one. (1Co 8:4)

The TWOT says that eliyl

comes perhaps from a root meaning “to be weak, deficient.” It is used primarily in Scripture to describe vain objects of worship, i.e. the gods of this world, whether literal idols made with hands, riches, or deceitful men. In Lv 19:4, its first appearance, the word is parallel to “molten gods” (cf. Lv 26:1). It is also applied to any works of one’s hands as an object of worship (Is 2:8; Hab 2:18). In Isaiah’s day, Jerusalem and Samaria were described as kingdoms of idols, i.e. a people who worshipped vain things (Is 10:10,11). Such idols were classed along with divination and lies (Je 14:14). They were clearly good for nothing (Is 2:20; 31:7). They even included people in whom men trusted but who were deceitful and of no value (Job 13:4; Isa 19:3; Zech 11:17). In Scripture they are contrasted to the true God, the Lord, the Creator (Ps 96:5) and before him they tremble (Isa 19:1), are put to shame (Ps 97:7), and are destroyed (Is 2:18) (Harris, R L, Archer, G L & Waltke, B K Theological Wordbook of the Old Testament. Moody Press or  Logos software version) 

Eliyl here in Isa 2:8 is translated in the Septuagint (LXX) by the Greek word bdelugma (from bdelusso = emit a foal odor, from bdeo = to stink!) which is literally a foul (as that which causes a stench), loathsome, detestable or abominable thing (used in the Lxx of 1K 11:6, 2Ki 16:3 "abominations"). Bdelugma thus is that which is (or at least should be) extremely hated, abhorred or disgusting. Indeed idols are utterly detestable and cause a stench in God's nostrils! We as men, do not fully comprehend God's utter hatred of idols and if we did I dare say we would be horrified that we still choose to trifle with them from time to time! In Rev 17:4 bdelugma is used in the description of Babylon...

And the woman was clothed in purple and scarlet, and adorned with gold and precious stones and pearls, having in her hand a gold cup full of abominations and of the unclean things of her immorality (Revelation 17:4-note)

Tony Garland writes that full of abominations is the same word here in Isa 2:8 (bdelugma) and the idea is...

“Anything that must not be brought before God because it arouses his wrath.”

“Anything connected with idolatry.”

God warned Israel through Moses:

When you come into the land which the LORD your God is giving you, you shall not learn to follow the abominations (Lxx = bdelugma) of those nations. There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination (Lxx = bdelugma) to the LORD, and because of these abominations (Lxx = bdelugma) the LORD your God drives them out from before you. (Dt 18:9, 10, 11, 12)

She (Babylon) is the mother of harlots and of abominations of the earth (Rev. 17:5-note). Thus, she birthed the abominations which are found in the cup which she serves. From this, we know that the woman is not just a figure of the time of the end, but has her roots stretching back to early history. Thus, both the Harlot and the Seven Heads on the Beast which she rides stretch back to early history. See Babylon of Old.

In this passage Isaiah describes Judah's wanton willful affront of God's clear and chief command...

I am the LORD your God, Who brought you out of the land of Egypt, out of the house of slavery. You shall have no other gods before Me. (Ex 20:2, 3)

They worship the work of their hands - This is just another way to say we worship ourselves when we worship the work of our hands and fingers!

Smith adds that...

Chuck Smith writes that in Is 2:9-21...

The Lord will bring down the proud and shake the earth. (Re 6:12-17; He 12:26)

Humbled (07817) (shachach/sahah) (Is 2:9-note, Is 2:11-note, Is 2:17-note) means to be bowed down, prostrated, humbled which is  the sense in this passage. It can also mean to bow in homage (Pr 14:19), to bow (as a mourner Ps 35:14, 38:7), to crouch (as a wild beast, Job 38:40). Later in Isaiah shachach is used of laying low a city or city walls (Is 25:12, 26:5).

Sachach/sahah - 21v in the OT - Job 9:13; 38:40; Ps 10:10; 35:14; 38:6; 42:5, 6, 11; 43:5; 107:39; Pr 14:19; Eccl 12:4; Isa. 2:9, 11, 17; 5:15; 25:12; 26:5; 29:4; 60:14; Hab 3:6 and is rendered in the NAS as been humbled(1), bow down(1), bowed down(3), bowing(1), bows down(1), bring down(1), brought low(1), collapsed(1), crouch(2), despair(4), humbled(3), prostrate(1), sing softly(1).

Abased (08213) (shaphel/sapal [word study]) (Frequent in Isaiah -  Is 2:9, 11, 12, 17; 5:15; 10:33; 13:11; 25:11, 12; 26:5; 29:4; 32:19; 40:4; 57:9) conveys the basic sense of to be low physically, which leads to the more important figurative meanings of abasement, humbling, humility

The NIV has "man will be brought low" but this is a doubtful translation of the verb shaphel/sapal.

But do not forgive them: (But - Is 27:11; Joshua 24:19; Jeremiah 18:23; Mark 3:29)
