Genesis 18:29

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.”

29He spoke to him yet again, and said, “What if there are forty found there?” He said, “I will not do it for the forty’s sake.”

30He said, “Oh don’t let the Lord be angry, and I will speak. What if there are thirty found there?” He said, “I will not do it if I find thirty there.”

31He said, “See now, I have taken it on myself to speak to the Lord. What if there are twenty found there?” He said, “I will not destroy it for the twenty’s sake.”

32He said, “Oh don’t let the Lord be angry, and I will speak just once more. What if ten are found there?” He said, “I will not destroy it for the ten’s sake.”

33The LORD went his way as soon as he had finished communing with Abraham, and Abraham returned to his place.
