Genesis 24:7-9

New Revised Standard Version Catholic Edition

⁷ The Lord, the God of heaven, who took me from my father’s house and from the land of my birth, and who spoke to me and swore to me, ‘To your offspring I will give this land,’ he will send his angel before you, and you shall take a wife for my son from there. ⁸ But if the woman is not willing to follow you, then you will be free from this oath of mine; only you must not take my son back there.” ⁹ So the servant put his hand under the thigh of Abraham his master and swore to him concerning this matter.
