Genesis 28:5-7

Then Isaac sent Jacob on his way to Paddan-Aram, the land of his grandfather Bethuel the Aramean, to the home of Laban, Bethuel’s son and the brother of Rebekah, the mother of Jacob and Esau. Esau had learned that Isaac had blessed Jacob and had sent him away to Paddan-Aram to find a wife there, and that while blessing him, Isaac had instructed him, “Don’t marry a Canaanite woman.” Furthermore, Esau found out that Jacob had obeyed his parents and fled to Paddan-Aram.
