Genesis 18:23-25

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

24There are perhaps fifty righteous within the city: wilt thou also destroy and not forgive the place for the sake of the fifty righteous that are therein?

25Far be it from thee to do so, to slay the righteous with the wicked, that the righteous should be as the wicked — far be it from thee! Will not the Judge of all the earth do right?
