Genesis 18:26

24What if there are fifty righteous within the city? Will you consume and not spare the place for the fifty righteous who are in it?

25May it be far from you to do things like that, to kill the righteous with the wicked, so that the righteous should be like the wicked. May that be far from you. Shouldn’t the Judge of all the earth do right?”

26The LORD said, “If I find in Sodom fifty righteous within the city, then I will spare the whole place for their sake.”

27Abraham answered, “See now, I have taken it on myself to speak to the Lord, although I am dust and ashes.

28What if there will lack five of the fifty righteous? Will you destroy all the city for lack of five?” He said, “I will not destroy it if I find forty-five there.”
