Genesis 22:15-19

15And the angel of Yhwh called unto Abraham out of heaven the second time, 16And said, By myself have I sworn, saith Yhwh, for 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 heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies;1 18And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice. 19So Abraham returned unto his young men, and they rose up and went together to Beer–sheba; and Abraham dwelt at Beer–sheba.
