Genesis 24:14-15

14This is my request. I will ask one of them, ‘Please give me a drink from your jug.’ If she says, ‘Yes, have a drink, and I will water your camels, too!’—let her be the one you have selected as Isaac’s wife. This is how I will know that you have shown unfailing love to my master.”

15Before he had finished praying, he saw a young woman named Rebekah coming out with her water jug on her shoulder. She was the daughter of Bethuel, who was the son of Abraham’s brother Nahor and his wife, Milcah.
