Genesis 18:22

20And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous;

21I 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.

22And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD.

23And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked?

24Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein?
