Genesis 18:26-28

So the LORD said, “If I find in Sodom fifty righteous within the city, then I will spare the whole place on their account.” And Abraham replied, “Now behold, I have ventured to speak to the Lord, although I am but dust and ashes. Suppose the fifty righteous are lacking five, will You destroy the whole city because of five?” And He said, “I will not destroy it if I find forty-five there.”
