Genesis 24:9

7The LORD, the God of heaven—who took me from my father’s house, and from the land of my birth, who spoke to me, and who swore to me, saying, ‘I will give this land to your offspring—he will send his angel before you, and you shall take a wife for my son from there.

8If the woman isn’t willing to follow you, then you shall be clear from this oath to me. Only you shall not bring my son there again.”

9The servant put his hand under the thigh of Abraham his master, and swore to him concerning this matter.

10The servant took ten of his master’s camels, and departed, having a variety of good things of his master’s with him. He arose, and went to Mesopotamia, to the city of Nahor.

11He made the camels kneel down outside the city by the well of water at the time of evening, the time that women go out to draw water.
