Genesis 18:26-29
English Standard Version
27Abraham answered and said, "Behold, I have undertaken to speak to the Lord, I who am but dust and ashes.
28Suppose five of the fifty righteous are lacking. Will you destroy the whole city for lack of five?" And he said, "I will not destroy it if I find forty-five there."
29Again he spoke to him and said, "Suppose forty are found there." He answered, "For the sake of forty I will not do it."
