Genesis 18:2, 17, 22, 31

When he raised his eyes and looked up, behold, three men were standing [a little distance] from him. When he saw them, he ran from the tent door to meet them and bowed down [with his face] to the ground

The LORD said, “Shall I keep secret from Abraham [My friend and servant] what I am going to do, [Gal 3:8]

Now the [two] men (angelic beings) turned away from there and went toward Sodom, but Abraham remained standing before the LORD.

And he said, “Now behold, I have decided to speak to the Lord [again]. Suppose [only] twenty [righteous people] are found there?” And the Lord said, “I will not destroy it for the sake of the twenty.”
