Abraham had taken another wife, whose name was Keturah.
So Isaac called for Jacob and blessed him. Then he commanded him: “Do not marry a Canaanite woman.
Isaac brought her into the tent of his mother Sarah, and he married Rebekah. So she became his wife, and he loved her; and Isaac was comforted after his mother’s death.
She bore him Zimran, Jokshan, Medan, Midian, Ishbak and Shuah.
