Genesis 22:16-17

¹⁶and said, By myself have I sworn, saith Jehovah, because thou hast done this thing, and hast not withheld thy son, thine only son, ¹⁷that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heavens, and as the sand which is upon the seashore. And thy seed shall possess the gate of his enemies.
