Genesis 18:26-28

The LORD said, “If I find fifty good people in the city of Sodom, I will save the whole city because of them.” Then Abraham said, “Though I am only dust and ashes, I have been brave to speak to the Lord. What if there are only forty-five good people in the city? Will you destroy the whole city for the lack of five good people?” The LORD said, “If I find forty-five there, I will not destroy the city.”
