Genesis 24:8-10

Revised Standard Version

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.

¹⁰ Then the servant took ten of his master’s camels and departed, taking all sorts of choice gifts from his master; and he arose, and went to Mesopota′mia, to the city of Nahor.
