Genesis 18:30-33

Then he said, “Let not the Lord be angry, and I will speak: Suppose thirty should be found there?” So He said, “I will not do it if I find thirty there.” And he said, “Indeed now, I have taken it upon myself to speak to the Lord: Suppose twenty should be found there?” So He said, “I will not destroy it for the sake of twenty.” Then he said, “Let not the Lord be angry, and I will speak but once more: Suppose ten should be found there?” And He said, “I will not destroy it for the sake of ten.” So the LORD went His way as soon as He had finished speaking with Abraham; and Abraham returned to his place.
