Genesis 18:27, 30-32

Abraham spoke up again and said, “I am just a man formed from earth’s dust and ashes but allow me to be so bold as to ask you, my Lord.

Abraham paused—then he said, “Lord, please don’t be offended with me, and let me speak . . . What if there are only thirty?” YAHWEH answered, “Alright. If I find only thirty, I will spare the city.” Abraham ventured even further, asking, “Allow me to dare speak this way to you, my Lord. But what if you find there only twenty righteous?” YAHWEH answered, “Alright. For the sake of the twenty I will not destroy the city.” 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.”
