Genesis 24:14-15

14I will say to one of the young women, “Please let me have a drink of water from your pot.” If she is the right woman for your servant Isaac to marry, please may she say, “Yes, drink. Then I will give water to your camels also”. If that happens, then I will know that you have kept your promise to my master.’

15The servant was still praying when Rebekah came to the well. She had her pot on her shoulder. Rebekah was the daughter of Bethuel, who was the son of Milcah. Milcah was the wife of Abraham's brother, Nahor.
