Genesis 28:1-9 ESV
Then Isaac called Jacob and blessed him and directed him, “You must not take a wife from the Canaanite women. Arise, go to Paddan-aram to the house of Bethuel your mother’s father, and take as your wife from there one of the daughters of Laban your mother’s brother. God Almighty bless you and make you fruitful and multiply you, that you may become a company of peoples. May he give the blessing of Abraham to you and to your offspring with you, that you may take possession of the land of your sojournings that God gave to Abraham!” Thus Isaac sent Jacob away. And he went to Paddan-aram, to Laban, the son of Bethuel the Aramean, the brother of Rebekah, Jacob’s and Esau’s mother.
Now Esau saw that Isaac had blessed Jacob and sent him away to Paddan-aram to take a wife from there, and that as he blessed him he directed him, “You must not take a wife from the Canaanite women,” and that Jacob had obeyed his father and his mother and gone to Paddan-aram. So when Esau saw that the Canaanite women did not please Isaac his father, Esau went to Ishmael and took as his wife, besides the wives he had, Mahalath the daughter of Ishmael, Abraham’s son, the sister of Nebaioth.
