16 And said, By myself have I sworn, says the LORD, for because you have done this thing, and have not withheld your son, your only son:

17 That in blessing I will bless you, and in multiplying I will multiply your descendants as the stars of the heaven, and as the sand which is upon the seashore; and your descendants shall possess the gate of their enemies;

18 And in your descendants shall all the nations of the earth be blessed; because you have obeyed my voice.
