Genesis 18:31-33

Then Abraham said, “Since I have dared to speak to the Lord, let me continue—suppose there are only twenty?” And the LORD replied, “Then I will not destroy it for the sake of the twenty.” Finally, Abraham said, “Lord, please don’t be angry with me if I speak one more time. Suppose only ten are found there?” And the LORD replied, “Then I will not destroy it for the sake of the ten.” When the LORD had finished his conversation with Abraham, he went on his way, and Abraham returned to his tent.
