Genesis 18:2, 17, 22, 31

He looked up and noticed three men standing nearby. When he saw them, he ran to meet them and welcomed them, bowing low to the ground.

“Should I hide my plan from Abraham?” the LORD asked.

The other men turned and headed toward Sodom, but the LORD remained with Abraham.

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.”
