Therefore, O harlot (Isa 1:21; 23:15,16; Jer 3:1,6-8; Ho 2:5; Nah 3:4; Jn 4:10,18; Rev 17:5)

hear the word of the LORD (Ezek 13:2; 20:47; 34:7; 1Ki 22:19; Isa 1:10; 28:14; Hos 4:1; Am 7:16)

Because your lewdness was poured out (Ezek 16:15-22; 22:15; 23:8; 24:13; 36:25; La 1:9; Zeph 3:1)

your nakedness uncovered through your harlotries with your lovers (Ezek 23:10,18,29; Ge 3:7,10,11; Ps 139:11,12; Jer 13:22-26; Rev 3:18)

because of the blood of your sons which you gave to idols (Ezek 16:20,21; Jer 2:34)

Amplified  making you, Israel, an object of loathing and of mockery, a spectacle among the nations

(Ezek 23:9,10,22-30; Jer 4:30; 13:22,26; 22:20; La 1:8,19; Hos 2:3,10; Hos 8:10; Nah 3:5,6; Rev 17:16)

They shall see all your nakedness

The Net Bible Notes that...

Harlots suffered degradation when their nakedness was exposed (Jer 13:22, 26; Hos 2:12; Nah 3:5).

As MacArthur notes

I shall judge you, like women who commit adultery (Ezek 16:40; 23:45-47; Ge 38:11,24; Lev 20:10; Dt 22:22-24; Mt 1:18,19; Jn 8:3-5)

How were they judged? Moses writes...

If there is a man who commits adultery with another man's wife, one who commits adultery with his friend's wife, the adulterer and the adulteress shall surely be put to death. (Lev 20:10)

If a man is found lying with a married woman, then both of them shall die, the man who lay with the woman, and the woman; thus you shall purge the evil from Israel. If there is a girl who is a virgin engaged to a man, and another man finds her in the city and lies with her, then you shall bring them both out to the gate of that city and you shall stone them to death; the girl, because she did not cry out in the city, and the man, because he has violated his neighbor's wife. Thus you shall purge the evil from among you. (Dt 22:22-24)

shed blood are judged and and I will bring on you the blood of wrath and jealousy (Ezek 16:20,21,36; Ge 9:6; Ex 21:12; Nu 35:31; Ps 79:3-5; Jer 18:21; Zeph 1:17; Nah 1:2; Rev 16:6)

Wrath (02534) (chemah/hemah from yaham = to be hot) describes that which is hot and figuratively refers to hot displeasure, indignation and wrath. Chemah is used most often to describe God's anger against His unfaithful wife Israel

Jealousy - This is a term between lovers. God had abundantly showered His love upon His chosen people. Instead of reciprocating, they rebelled, thus incurring His jealous anger.

What is God's Word of truth on capital punishment? What is the blood of wrath and jealousy? Moses records that...

they will tear down your shrines ("brothel")," (Ezek 16:24,25,31; 7:22-24; Is 27:9)

strip you of your clothing (Ezek 16:10-20; 23:26,29; Is 3:16-24; Ho2:3,9-13)

They will incite a crowd against you (Hab 1:6-10; Jn 8:5-7)

Crowd - in context pictures Judah's lovers inciting other nations to wage war against her.

they will burn your houses with fire (Dt 13:16; 2Ki 25:9; Jer 39:8; 52:13; Micah 3:12)

execute judgments on you in the sight of many women (Amp "the nations")" (Ezek 5:8; 23:10,48; Dt 13:11; 22:21,24; Job 34:26)

I shall calm (rest) My fury against you (Ezek 5:13; 21:17; 2Sa21:14; Is1:24; Zech 6:8)

I shall be pacified and angry no more  (Ezek 39:29; Is 40:1,2; 54:9,10)

you have not remembered the days of your youth (Ezek 16:22; Ps 78:42; 106:13; Jer 2:32)

have enraged Me by all these things (Ezek 6:9; Dt 32:21; Ps 8:40; 95:10; Isa 63:10; Am 2:13; Acts 7:51; Eph 4:30)

Behold, everyone who quotes proverbs will quote this proverb concerning you, saying, 'Like mother, like daughter.' (Ezekiel 18:2,3; 1 Samuel 24:13) (Ezek 16:3,45; 1Ki 21:16; 2Ki17:11,15; 21:9; Ezra 9:1; Ps 106:35-38)

Like mother like daughter - In this context mother  refers to the Hittites (Ezek. 16:3 says to Judah/Jerusalem - your mother a Hittite). The point of the proverb is that Israel was as lewd and immoral as the original inhabitants of Canaan who were unspeakably debauched as discerned from archeological findings related to this time period. By way of practical application every mother should contemplate the far-reaching influence of her lips and her life before her children (fathers, this applies to your influence as well for generally "like father, like sons"! Be careful how you conduct yourself, not as unwise fathers but as wise fathers who are seeking to redeem the few short years of your life on earth for the days are evil.

Cooper writes that...

The next stage in the judgment of the orphan who became a queen, a harlot, and finally a convicted criminal was the revelation that her story would become a proverb (cf. Ezekiel 14:8). The proverb was, Like mother, like daughter. The point was that if Jerusalem wanted a shocking look at her disgraceful character and her dismal future, she could look at her cultural ancestors the Hittites and Amorites, who had transmitted their heritage of wickedness to Sodom, Samaria, and Jerusalem. In depravity and idolatry Israel had followed the bad example of the Canaanites and thus would be judged like them (Cooper, L. E.  Vol. 17: Ezekiel: The New American Commentary. Nashville: Broadman & Holman Publishers)

The Disciple's Study Bible writes that...

Now your older sister is Samaria who lives north of you with her daughters (Ezek 16:51; 23:4,11,31-33; Jer 3:8-11; Mic 1:5)

Samaria who lives north - North is literally "at thy left hand". This is clearly a reference to the northern 10 tribes who had their capital in Samaria. The Northern Kingdom was not older chronologically but was larger and the first to be judged by God in 722BC when she was defeated and taken into exile by the Assyrians.

Your younger sister - Judah whose capital was Jerusalem. Notice they are all referred to in feminine terms. They all fell into spiritual adultery or harlotry. Anyone reading this description who has a daughter has to be gripped by the tragic description. How it must have grieved the Father's heart! We need to recall this to mind the next time we contemplate making provision to commit a sin (see note Romans 13:14). Peter speaks to this point in his first letter writing...

And if you address as Father the One who impartially judges according to each man's work, conduct yourselves in fear during the time of your stay upon earth; 18 knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, but with precious blood, as of a lamb unblemished and spotless, the blood of Christ. (See notes 1 Peter 1:17; 1:18; 1:19) (Comment: The point is that believers need to be reading and meditating on truths such as found in Ezekiel 16, that they might maintain a healthy, reverential fear of the Lord and of the certainty of reaping the consequences of sinning. This healthy fear is set in the background of recalling the high cost to the Father to provide us with so great a salvation -- His Son's precious blood. Next time you are tempted to get angry, to lash out in hostility at your mate or child, to commit egregious sin, to overtly rebel against Truth, etc -- before you react...Think...Remember...Recall what if cost the Father. Without that provision, that sin you would commit would otherwise be your death sentence [see James 2:10]. Then, instead of reacting in anger, etc, act with an attitude of gratitude and contrition and humility, thankful that you now have the strength of His indwelling Spirit to walk in a manner that pleases your Father rather than grieves Him! Amen.)

Pray Psalm 119:38...

Establish Thy word to Thy servant, As that which produces reverence for Thee.

In his comments on Psalm 119:38 Charles Spurgeon wrote

Make me sure of Thy sure word: make it sure to me and make me sure of it. If we possess the spirit of service, and yet are troubled with sceptical thoughts we cannot do better than pray to be established in the truth. Times will arise when every doctrine and promise seems to be shaken, and our mind gets no rest: then we must appeal to God for establishment in the faith, for he would have all his servants to be well instructed and confirmed in his word. But we must mind that we are the Lord's servants, for else we shall not long be sound in his truth. Practical holiness is a great help towards doctrinal certainty: if we are God's servants he will confirm his word in our experience. "If any man will do his will, he shall know of the doctrine"; and so know it as to be fully assured of it. Atheism in the heart is a horrible plague to a God fearing man, it brings more torment with it than can well be described; and nothing but a visitation of grace can settle the soul after it has been violently assailed thereby. Vanity or falsehood is bad for the eyes, but it is even worse when it defiles the understanding and casts a doubt upon the word of the living God.

Who is devoted to Thy fear, or simply -- "to thy fear." That is, make good Thy word to godly fear: wherever it exists; strengthen the whole body of reverent men. Stablish Thy word, not only to me, but to all the godly ones under the sun. Or, again, it may mean -- "Stablish Thy word to Thy fear," namely, that men may be led to fear thee; since a sure faith in the divine promise is the fountain and foundation of godly fear.

Men will never worship a God in Whom they do not believe. More faith will lead to more godly fear. We cannot look for the fulfilment of promises in our experience unless we live under the influence of the fear of the Lord: establishment in grace is the result of holy watchfulness and prayerful energy. We shall never be rooted and grounded in our belief unless we daily practise what we profess to believe. Full assurance is the reward of obedience. Answers to prayer are given to those whose hearts answer to the Lord's command.

If we are devoted to God's fear we shall be delivered from all other fear. He has no fear as to the truth of the word who is filled with fear of the Author of the word.

Scepticism is both the parent and the child of impiety; but strong faith both begets piety and is begotten of it. We commend this whole verse to any devout man whose tendency is to scepticism: it will be an admirable prayer for use in seasons of unusually strong misgivings. Spurgeon's Note)

your younger sister, who lives south of you, is Sodom (Ezek 16:48,49,53-56,61; Ge 13:11-13; 18:20-33; 19:24,25; Dt 29:23; 32:32; Isa 1:9,10; Jer 23:14; Lam 4:6; Lu 17:28-30; 2Pe 2:6; Jude 1:7; Rev 11:8)

Lives south - literally "dwelling on thy right hand"

Sodom - Used here to symbolize the southern kingdom and Jerusalem. This is the first of the 6 uses of the term Sodom by Ezekiel, all of them in Ezekiel 16.

In the book of the Revelation Jerusalem is again referred to as Sodom ...

And their dead bodies will lie in the street of the great city which mystically is called Sodom and Egypt, where also their Lord was crucified. (From his note on Revelation 11:8 Tony Garland writes "Both Sodom and Egypt typify cities which were opposed and judged by God. Sodom was an exceedingly wicked city which was overthrown for her sins by God’s judgment (Ge 13:13; 19:24). Egypt was the nation which held Israel in bondage and was judged by plagues prior to the Exodus (Ex. 1:13-14; 3:7; 20:2). Jerusalem, in her godless state, is likened to both the wicked city and the wicked nation. Even though the two witnesses exhibit a Jewish ministry located in Jerusalem, they are rejected by the majority of the inhabitants—their fellow Jews.

When Moses sang a song predicting the apostasy of Israel upon entering the Promised Land after his death, he referred to the Jewish nation as a nation void of counsel whose vine is of the vine of Sodom and of the fields of Gomorrah (Dt. 32:28-32). Isaiah used a similar analogy when describing God’s rejection of Israel’s insincere sacrifices:

Hear the word of the LORD you rulers of Sodom; give ear to the law of our God, you people of Gomorrah: ‘To what purpose is the multitude of your sacrifices to Me?’ (Isa. 1:10).

The sin of Jerusalem is said to be as the sin of Sodom in that it was flaunted openly (Isa 3:8).6 Even the apostate prophets are likened to the inhabitants of Sodom and Gomorrah (Jer 23:14). When rejected by the cities of the lost sheep of the house of Israel, Jesus indicated that the cities which did not receive the apostles or their words would be considered worse off than Sodom and Gomorrah in the day of judgment (Mt 10:14-15; Luke 10:12). Although Jerusalem is here referred to as Sodom, Isaiah also indicated that Babylon’s eventual overthrow would be like that of Sodom and Gomorrah (Isa. 13:19). Elsewhere, Ezekiel describes the Northern Kingdom (Samaria) and the Southern Kingdom (Jerusalem) as idolatrous sisters, both of which committed harlotry in their youth while in Egypt (Ezekiel 23:2-4, 19, 27). Comparison with Egypt recalls the idolatrous golden calf which Israel made upon departure from Egypt (Ex. 32:4, 24).

with her daughters (Ezek 16:27; 26:6; Ge 14:8; 19:29; Hos 11:8)
