Genesis 22:15-19

15And the angel of the LORD called to Abraham from heaven the second time, 16And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thy only son : 17That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of heaven, and as the sand which is on 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 to his young men, and they rose and went together to Beersheba; and Abraham dwelt at Beersheba.
