Genesis 28:1-9

So Isaac called for Jacob, blessed him, and said, “You must not marry any of these Canaanite women. Instead, go at once to Paddan-aram, to the house of your grandfather Bethuel, and marry one of your uncle Laban’s daughters. May God Almighty bless you and give you many children. And may your descendants multiply and become many nations! May God pass on to you and your descendants the blessings he promised to Abraham. May you own this land where you are now living as a foreigner, for God gave this land to Abraham.” So Isaac sent Jacob away, and he went to Paddan-aram to stay with his uncle Laban, his mother’s brother, the son of Bethuel the Aramean. Esau knew that his father, Isaac, had blessed Jacob and sent him to Paddan-aram to find a wife, and that he had warned Jacob, “You must not marry a Canaanite woman.” He also knew that Jacob had obeyed his parents and gone to Paddan-aram. It was now very clear to Esau that his father did not like the local Canaanite women. So Esau visited his uncle Ishmael’s family and married one of Ishmael’s daughters, in addition to the wives he already had. His new wife’s name was Mahalath. She was the sister of Nebaioth and the daughter of Ishmael, Abraham’s son.
