Genesis 24:6-10

6“Make sure that you do not take my son back there,” Abraham said. 7“The LORD, the God of heaven, who brought me out of my father’s household and my native land and who spoke to me and promised me on oath, saying, ‘To your offspring Or seed I will give this land’—he will send his angel before you so that you can get a wife for my son from there. 8If the woman is unwilling to come back with you, then you will be released from this oath of mine. Only do not take my son back there.”

9So the servant put his hand under the thigh of his master Abraham and swore an oath to him concerning this matter. 10Then the servant left, taking with him ten of his master’s camels loaded with all kinds of good things from his master. He set out for Aram Naharaim That is, Northwest Mesopotamia and made his way to the town of Nahor.
