Genesis 18:17-19

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.”
