Genesis 18:26-32

26The LORD said, “If I find fifty righteous people in the city of Sodom, I will spare the whole place for their sake.” 27Then Abraham spoke up again: “Now that I have been so bold as to speak to the Lord, though I am nothing but dust and ashes,

28what if the number of the righteous is five less than fifty? Will you destroy the whole city for lack of five people?” “If I find forty-five there,” he said, “I will not destroy it.”

29Once again he spoke to him, “What if only forty are found there?” He said, “For the sake of forty, I will not do it.”

30Then he said, “May the Lord not be angry, but let me speak. What if only thirty can be found there?” He answered, “I will not do it if I find thirty there.”

31Abraham said, “Now that I have been so bold as to speak to the Lord, what if only twenty can be found there?” He said, “For the sake of twenty, I will not destroy it.”

32Then he said, “May the Lord not be angry, but let me speak just once more. What if only ten can be found there?” He answered, “For the sake of ten, I will not destroy it.”
