Genesis 18:26

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

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?

And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, which [am but] dust and ashes:

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].
