Genesis 28:5-6

28:5 So Isaac sent Jacob on his way, and he went to Paddan Aram, to Laban son of Bethuel the Aramean and brother of Rebekah, the mother of Jacob and Esau.

28:6 Esau saw that Isaac had blessed Jacob and sent him off to Paddan Aram to find a wife there. As he blessed him, Isaac commanded him, “You must not marry a Canaanite woman.”
