Genesis 18:16-19

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.”
