⁸ While Abraham was in Ur, Jehovah told him to move to another land, which turned out to be Canaan. At that time Jehovah promised Abraham: “I shall make a great nation out of you and I shall bless you and I will make your name great; . . . and all the families of the ground will certainly bless themselves by means of you.”a (Genesis 12:1-3) Thereafter, God gradually added details to what we rightly speak of as the Abrahamic covenant: Abraham’s seed, or heir, would inherit the Promised Land; his seed would lead to unnumbered offspring; Abraham and Sarah would be the source of kings.​—Genesis 13:14-17; 15:4-6; 17:1-8, 16; Psalm 105:8-10.
