Genesis 28:1-9

So Isaac called Jacob and blessed him and charged him, and said to him, “You shall not marry one of the women of Canaan. Arise, go to Paddan-aram, to the house of Bethuel your mother’s father; and take from there as a wife for yourself one of the daughters of Laban your mother’s brother. May God Almighty bless you and make you fruitful and multiply you, so that you may become a [great] company of peoples. May He also give the blessing of Abraham to you and your descendants with you, that you may inherit the [promised] land of your sojournings, which He gave to Abraham.” Then Isaac sent Jacob away, and he went to Paddan-aram, to Laban, son of Bethuel the Aramean, the brother of Rebekah, the mother of Jacob and Esau. Now Esau noticed that Isaac had blessed Jacob and sent him to Paddan-aram to take a wife for himself from there, and that as he blessed him he gave him a prohibition, saying, “You shall not take a wife from the daughters of Canaan,” and that Jacob obeyed his father and his mother and had gone to Paddan-aram. So Esau realized that [his two wives] the daughters of Canaan displeased Isaac his father; and [to appease his parents] Esau went to [the family of] Ishmael and took as his wife, in addition to the wives he [already] had, Mahalath the daughter of Ishmael, Abraham’s son, the sister of Nebaioth [Ishmael’s firstborn son].
