Genesis 18:16-19

Then the men got up from there, and looked toward Sodom; and Abraham walked with them to send them on the way. The LORD said, “Shall I keep secret from Abraham [My friend and servant] what I am going to do, [Gal 3:8] since Abraham is destined to become a great and mighty nation, and all the nations of the earth will be blessed through him? [Gen 12:2, 3] For I have known (chosen, acknowledged) him [as My own], so that he may teach and command his children and [the sons of] his household after him to keep the way of the LORD by doing what is righteous and just, so that the LORD may bring upon Abraham what He has promised him.”
