Genesis 18:27, 30-32

Then Abraham said, “Though I am only dust and ashes, I have been brave to speak to the Lord.

Then Abraham said, “Lord, please don’t be angry with me, but let me ask you this. If you find only thirty good people in the city, will you destroy it?” He said, “If I find thirty good people there, I will not destroy the city.” Then Abraham said, “I have been brave to speak to the Lord. But what if there are twenty good people in the city?” He answered, “If I find twenty there, I will not destroy the city.” Then Abraham said, “Lord, please don’t be angry with me, but let me bother you this one last time. What if you find ten there?” He said, “If I find ten there, I will not destroy it.”
