Genesis 18:2, 17, 22, 31

Abraham looked up and saw three men standing nearby. When he saw them, he hurried from the entrance of his tent to meet them and bowed low to the ground.

Then the LORD said, “Shall I hide from Abraham what I am about to do?

The men turned away and went toward Sodom, but Abraham remained standing before the LORD.

Abraham said, “Now that I have been so bold as to speak to the Lord, what if only twenty can be found there?” He said, “For the sake of twenty, I will not destroy it.”
