Genesis 18:22-25

The other men turned and headed toward Sodom, but the LORD remained with Abraham. Abraham approached him and said, “Will you sweep away both the righteous and the wicked? Suppose you find fifty righteous people living there in the city—will you still sweep it away and not spare it for their sakes? Surely you wouldn’t do such a thing, destroying the righteous along with the wicked. Why, you would be treating the righteous and the wicked exactly the same! Surely you wouldn’t do that! Should not the Judge of all the earth do what is right?”
