Genesis 18:16-22, 32-33

Then the men got up from their meal and looked out toward Sodom. As they left, Abraham went with them to send them on their way. “Should I hide my plan from Abraham?” the LORD asked. “For Abraham will certainly become a great and mighty nation, and all the nations of the earth will be blessed through him. I have singled him out so that he will direct his sons and their families to keep the way of the LORD by doing what is right and just. Then I will do for Abraham all that I have promised.” So the LORD told Abraham, “I have heard a great outcry from Sodom and Gomorrah, because their sin is so flagrant. I am going down to see if their actions are as wicked as I have heard. If not, I want to know.” The other men turned and headed toward Sodom, but the LORD remained with Abraham.

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.
