Genesis 22:16-18

Young's Literal Translation

¹⁶ and saith, `By Myself I have sworn -- the affirmation of Jehovah -- that because thou hast done this thing, and hast not withheld thy son, thine only one --

¹⁷ that blessing I bless thee, and multiplying I multiply thy seed as stars of the heavens, and as sand which [is] on the sea-shore; and thy seed doth possess the gate of his enemies;

¹⁸ and blessed themselves in thy seed have all nations of the earth, because that thou hast hearkened to My voice.'
