Genesis 18:26-32

18:26 So the Lord replied, “If I find in the city of Sodom fifty godly people, I will spare the whole place for their sake.”

18:27 Then Abraham asked, “Since I have undertaken to speak to the Lord (although I am but dust and ashes), 18:28 what if there are five less than the fifty godly people? Will you destroy the whole city because five are lacking?” He replied, “I will not destroy it if I find forty-five there.”

18:29 Abraham spoke to him again, “What if forty are found there?” He replied, “I will not do it for the sake of the forty.”

18:30 Then Abraham said, “May the Lord not be angry so that I may speak! What if thirty are found there?” He replied, “I will not do it if I find thirty there.”

18:31 Abraham said, “Since I have undertaken to speak to the Lord, what if only twenty are found there?” He replied, “I will not destroy it for the sake of the twenty.”

18:32 Finally Abraham said, “May the Lord not be angry so that I may speak just once more. What if ten are found there?” He replied, “I will not destroy it for the sake of the ten.”
