Genesis 22:16-18

16and said: “By Myself I have sworn, says the Lord, because you have done this thing, and have not withheld your son, your only son—

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

18In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.”
