Genesis 18:32-33

Then Abraham took a deep breath and asked, “Once more, please don’t let my Lord be angry with me if I make but one more request. What if you find only ten righteous?” And YAHWEH answered, “Alright. I will extend my mercy and not destroy the city for the sake of ten righteous.” YAHWEH finished speaking with Abraham. He immediately went on his way, and Abraham returned home.
