Genesis 28:1-9

Isaac called Jacob and blessed him and commanded him, “You must not marry a Canaanite woman. Go to the house of Bethuel, your mother’s father, in Northwest Mesopotamia. Laban, your mother’s brother, lives there. Marry one of his daughters. May God Almighty bless you and give you many children, and may you become a group of many peoples. May he give you and your descendants the blessing of Abraham so that you may own the land where you are now living as a stranger, the land God gave to Abraham.” So Isaac sent Jacob to Northwest Mesopotamia, to Laban the brother of Rebekah. Bethuel the Aramean was the father of Laban and Rebekah, and Rebekah was the mother of Jacob and Esau. Esau learned that Isaac had blessed Jacob and sent him to Northwest Mesopotamia to find a wife there. He also learned that Isaac had commanded Jacob not to marry a Canaanite woman and that Jacob had obeyed his father and mother and had gone to Northwest Mesopotamia. So Esau saw that his father Isaac did not want his sons to marry Canaanite women. Now Esau already had wives, but he went to Ishmael son of Abraham, and he married Mahalath, Ishmael’s daughter. Mahalath was the sister of Nebaioth.
