Genesis 25:22-24

During her pregnancy, Rebekah could feel twins thrashing and struggling with each other inside her womb. So she went to inquire of YAHWEH, saying, “Why do I have to live with this?” And YAHWEH answered her, saying, “The two sons in your womb will become two nations, and the two peoples within you will become rivals. One people will become stronger than the other, and the older will serve the younger.” And when the time came for Rebekah to give birth, sure enough, she had twins!
