Genesis 18:26-32

26So the Lord said, “If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.”

27Then Abraham answered and said, “Indeed now, I who am but dust and ashes have taken it upon myself to speak to the Lord:

28Suppose there were five less than the fifty righteous; would You destroy all of the city for lack of five?” So He said, “If I find there forty-five, I will not destroy it.”

29And he spoke to Him yet again and said, “Suppose there should be forty found there?” So He said, “I will not do it for the sake of forty.”

30Then he said, “Let not the Lord be angry, and I will speak: Suppose thirty should be found there?” So He said, “I will not do it if I find thirty there.”

31And he said, “Indeed now, I have taken it upon myself to speak to the Lord: Suppose twenty should be found there?” So He said, “I will not destroy it for the sake of twenty.”

32Then he said, “Let not the Lord be angry, and I will speak but once more: Suppose ten should be found there?” And He said, “I will not destroy it for the sake of ten.”
