Genesis 18:20-32 New American Bible (Revised Edition) (NABRE)
20 So the Lord said: The outcry against Sodom and Gomorrah is so great, and their sin so grave,[a] 21 that I must go down to see whether or not their actions are as bad as the cry against them that comes to me. I mean to find out.
22 As the men turned and walked on toward Sodom, Abraham remained standing before the Lord. 23 Then Abraham drew near and said: “Will you really sweep away the righteous with the wicked? 24 Suppose there were fifty righteous people in the city; would you really sweep away and not spare the place for the sake of the fifty righteous people within it? 25 Far be it from you to do such a thing, to kill the righteous with the wicked, so that the righteous and the wicked are treated alike! Far be it from you! Should not the judge of all the world do what is just?” 26 The Lord replied: If I find fifty righteous people in the city of Sodom, I will spare the whole place for their sake. 27 Abraham spoke up again: “See how I am presuming to speak to my Lord, though I am only dust and ashes! 28 What if there are five less than fifty righteous people? Will you destroy the whole city because of those five?” I will not destroy it, he answered, if I find forty-five there. 29 But Abraham persisted, saying, “What if only forty are found there?” He replied: I will refrain from doing it for the sake of the forty. 30 Then he said, “Do not let my Lord be angry if I go on. What if only thirty are found there?” He replied: I will refrain from doing it if I can find thirty there. 31 Abraham went on, “Since I have thus presumed to speak to my Lord, what if there are no more than twenty?” I will not destroy it, he answered, for the sake of the twenty. 32 But he persisted: “Please, do not let my Lord be angry if I speak up this last time. What if ten are found there?” For the sake of the ten, he replied, I will not destroy it.
