Genesis 18:24-25

24What if there are fifty righteous people in the city? Will you really sweep it away and not spare Or forgive; also in verse 26 the place for the sake of the fifty righteous people in it?

25Far be it from you to do such a thing—to kill the righteous with the wicked, treating the righteous and the wicked alike. Far be it from you! Will not the Judge of all the earth do right?”
