Genesis 18:23-32

Abraham approached [the LORD] and said, “Will You really sweep away the righteous (those who do right) with the wicked (those who do evil)? Suppose there are fifty righteous [people] within the city; will You really sweep it away and not spare it for the sake of the fifty righteous who are in it? Far be it from You to do such a thing—to strike the righteous with the wicked, so that the righteous and the wicked are treated alike. Far be it from You! Shall not the Judge of all the earth do right [by executing just and righteous judgment]?” So the LORD said, “If I find within the city of Sodom fifty righteous [people], then I will spare the entire place for their sake.” Abraham answered, “Now behold, I who am but dust [in origin] and ashes have decided to speak to the Lord. [Gen 3:19; Job 30:19] If five of the fifty righteous are lacking, will You destroy the entire city for lack of five?” And He said, “If I find [at least] forty-five [righteous people] there, I will not destroy it.” Abraham spoke to Him yet again and said, “Suppose [only] forty are found there.” And He said, “I will not do it for the sake of the forty [who are righteous].” Then Abraham said [to Him], “Oh, may the Lord not be angry, and I will speak; suppose thirty [righteous people] are found there?” And He said, “I will not do it if I find thirty there.” And he said, “Now behold, I have decided to speak to the Lord [again]. Suppose [only] twenty [righteous people] are found there?” And the Lord said, “I will not destroy it for the sake of the twenty.” Then Abraham said, “Oh may the Lord not be angry [with me], and I will speak only this once; suppose ten [righteous people] are found there?” And He said, “I will not destroy it for the sake of the ten.”
