Genesis 18:24-33

24Suppose there are fifty righteous within the city. Will you then sweep away the place and not spare it for the fifty righteous who are in it? 25Far be it from you to do such a thing, to put the righteous to death with the wicked, so that the righteous fare as the wicked! Far be that from you! Shall not the Judge of all the earth do what is just?” 26And the LORD said, “If I find at Sodom fifty righteous in the city, I will spare the whole place for their sake.” 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.” 30Then 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.” 31He said, “Behold, I have undertaken to speak to the Lord. Suppose twenty are found there.” He answered, “For the sake of twenty I will not destroy it.” 32Then 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.” 33And the LORD went his way, when he had finished speaking to Abraham, and Abraham returned to his place.
