Genesis 24:7-9

American Standard Version

⁷ Jehovah, the God of heaven, who took me from my father’s house, and from the land of my nativity, and who spake unto me, and who sware unto me, saying, Unto thy seed will I give this land; he will send his angel before thee, and thou shalt take a wife for my son from thence. ⁸ And if the woman be not willing to follow thee, then thou shalt be clear from this my oath; only thou shalt not bring my son thither again. ⁹ And the servant put his hand under the thigh of Abraham his master, and sware to him concerning this matter.
