Genesis 22:15-18

The Angel of the LORD called to Abraham from heaven a second time and said, “By Myself (on the basis of Who I Am) I have sworn [an oath], declares the LORD, that since you have done this thing and have not withheld [from Me] your son, your only son [of promise], indeed I will greatly bless you, and I will greatly multiply your seed like the stars of the heavens and like the sand on the seashore; and your seed shall possess the gate of their enemies [by conquering them]. [Heb 6:13, 14; 11:12] Through your seed all the nations of the earth shall be blessed, because you have heard and obeyed My voice.” [Gen 12:2, 3; 13:16; 22:18; 26:4; 28:14; Acts 3:25, 26; Gal 3:16]
