Genesis 28:1-9

And Isaac called Jacob, and blessed him, and charged him, and said unto him, Thou shalt not take a wife of the daughters of Canaan. Arise, go to Padan-aram, to the house of Bethuel thy mother's father; and take thee a wife from thence of the daughters of Laban thy mother's brother. And God Almighty bless thee, and make thee fruitful, and multiply thee, that thou mayest be a multitude of people; and give thee the blessing of Abraham, to thee, and to thy seed with thee; that thou mayest inherit the land wherein thou art a stranger, which God gave unto Abraham. And Isaac sent away Jacob: and he went to Padan-aram unto Laban, son of Bethuel the Syrian, the brother of Rebekah, Jacob's and Esau's mother. When Esau saw that Isaac had blessed Jacob, and sent him away to Padan-aram, to take him a wife from thence; and that as he blessed him he gave him a charge, saying, Thou shalt not take a wife of the daughters of Canaan; and that Jacob obeyed his father and his mother, and was gone to Padan-aram; and Esau seeing that the daughters of Canaan pleased not Isaac his father; then went Esau unto Ishmael, and took unto the wives which he had Mahalath the daughter of Ishmael Abraham's son, the sister of Nebajoth, to be his wife.
