Genesis 18:26

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

24 Peradventure there are fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that [are] in it?

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, who [am] dust and ashes, have taken upon me to speak to the Lord.

28 Peradventure there will 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 spoke to him yet again, and said, Peradventure there will be forty found there. And he said, I will not do [it] for forty's sake.
