Genesis 18:22-33 Revised Standard Version (RSV)
22 So the men turned from there, and went toward Sodom; but Abraham still stood before the Lord. 23 Then Abraham drew near, and said, “Wilt thou indeed destroy the righteous with the wicked? 24 Suppose there are fifty righteous within the city; wilt thou then destroy the place and not spare it for the fifty righteous who are in it? 25 Far be it from thee to do such a thing, to slay the righteous with the wicked, so that the righteous fare as the wicked! Far be that from thee! Shall not the Judge of all the earth do right?” 26 And the Lord said, “If I find at Sodom fifty righteous in the city, I will spare the whole place for their sake.” 27 Abraham answered, “Behold, I have taken upon myself to speak to the Lord, I who am but dust and ashes. 28 Suppose five of the fifty righteous are lacking? Wilt thou destroy the whole city for lack of five?” And he said, “I will not destroy it if I find forty-five there.” 29 Again he spoke to him, and said, “Suppose forty are found there.” He answered, “For the sake of forty I will not do it.” 30 Then he said, “Oh let not the Lord be angry, and I will speak. Suppose thirty are found there.” He answered, “I will not do it, if I find thirty there.” 31 He said, “Behold, I have taken upon myself to speak to the Lord. Suppose twenty are found there.” He answered, “For the sake of twenty I will not destroy it.” 32 Then he said, “Oh let not the Lord be angry, and I will speak again but this once. Suppose ten are found there.” He answered, “For the sake of ten I will not destroy it.” 33 And the Lord went his way, when he had finished speaking to Abraham; and Abraham returned to his place.
