What did the LORD tell Rebekah about the twins struggling in her womb?

Answer: The older will serve the younger

"Two nations are in your womb... one people will be stronger than the other, and the older will serve the younger."

“But the children inside her struggled with each other, and she said, “Why is this happening to me?” So Rebekah went to inquire of the LORD, and He declared to her: “Two nations are in your womb, and two peoples from within you will be separated; one people will be stronger than the other, and the older will serve the younger.””— Genesis 25:22-23 (BSB)
