Genesis 24:12

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

The 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.

He 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.

Behold, I am standing by the spring of water. The daughters of the men of the city are coming out to draw water.

Let it happen, that the young lady to whom I will say, ‘Please let down your pitcher, that I may drink,’ then she says, ‘Drink, and I will also give your camels a drink,’—let her be the one you have appointed for your servant Isaac. By this I will know that you have shown kindness to my master.”

Before he had finished speaking, behold, Rebekah came out, who was born to Bethuel the son of Milcah, the wife of Nahor, Abraham’s brother, with her pitcher on her shoulder.
