Genesis 18:2, 17, 22, 31

When he lifted up his eyes and looked, behold, three men were standing opposite him; and when he saw them, he ran from the tent door to meet them and bowed himself to the earth

The LORD said, “Shall I hide from Abraham what I am about to do

Then the men turned away from there and went toward Sodom, while Abraham was still standing before the LORD.

And he said, “Now behold, I have ventured to speak to the Lord; suppose twenty are found there?” And He said, “I will not destroy it on account of the twenty.”
