Genesis 22:16-17

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]
