Gen. 18.20, 21: "And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous; I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know."
Gen. 18:
[23] And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked?
[24] Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein?
[25] That be far from thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from thee: Shall not the Judge of all the earth do right?
[26] And the LORD said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.
[27] And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, which am but dust and ashes:
[28] Peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, If I find there forty and five, I will not destroy it.
[29] And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for forty's sake.
[30] And he said unto him, Oh let not the Lord be angry, and I will speak: Peradventure there shall thirty be found there. And he said, I will not do it, if I find thirty there.
[31] And he said, Behold now, I have taken upon me to speak unto the Lord: Peradventure there shall be twenty found there. And he said, I will not destroy it for twenty's sake.
[32] And he said, Oh let not the Lord be angry, and I will speak yet but this once: Peradventure ten shall be found there. And he said, I will not destroy it for ten's sake.
Isaiah 3.8,9
"For Jerusalem is ruined, and Judas is fallen: because their tongue and their doings are against the LORD, to provoke the eyes of his glory. The show of their countenance doth witness against them; and they declare their sin as Sodom, they hide it not. Woe unto their soul! for they have rewarded evil unto themselves."
Jeremiah 23.14 "I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness: they are all of them unto me as Sodom, and the inhabitants thereof as Gomorrah."
Ezek. 16:
[49] Behold, this was the iniquity of thy sister Sodom, pride, fulness of bread, and abundance of idleness was in her and in her daughters, neither did she strengthen the hand of the poor and needy.
[50] And they were haughty, and committed abomination before me: therefore I took them away as I saw good.
Ezekiel 16.46 - 48 "And thine elder sister is Samara, she and her daughters that dwell at they left hand: and thy younger sister, that dwelled at thy right hand, is Sodom and her daughters. Yet hast thou not walked after their ways, nor done after their abominations: but, as if that were a very little thing, thou was corrupted more than they in all their ways. As I live, saith the Lord GOD, Sodom thy sister hath not done, she nor her daughters, as thou hast done, thou and thy daughters."
Matt. 11:
[23] And thou, Capernaum, which art exalted unto heaven, shalt be brought down to hell: for if the mighty works, which have been done in thee, had been done in Sodom, it would have remained until this day.
2 Peter 2:
[6] And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly;
Jude 1.4, 7, 8
"For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ. Even as Sodom and Gomorrah, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire. Likewise also these filthy dreamers defile the flesh, despise dominion, and speak evil of dignities."
