Romans 9:10-13

10And not only so, but also when Rebekah had conceived children by one man, our forefather Isaac,

11though they were not yet born and had done nothing either good or bad—in order that God's purpose of election might continue, not because of works but because of him who calls—

12she was told, "The older will serve the younger."

13As it is written, "Jacob I loved, but Esau I hated."
