(1) So Isaac sent for Jacob and blessed him. He instructed him, saying, “You shall not take a wife from among the Canaanite women.(2) Up, go to Paddan-aram, to the house of Bethuel, your mother’s father, and take a wife there from among the daughters of Laban, your mother’s brother.(3) May El Shaddai*El Shaddai See note at 17.1. bless you, make you fertile and numerous, so that you become an assembly of peoples.(4) May you and your offspring be granted the blessing of Abraham, that you may possess the land where you are sojourning, which God assigned to Abraham.”(5) Then Isaac sent Jacob off, and he went to Paddan-aram, to Laban the son of Bethuel the Aramean, the brother of Rebekah, mother of Jacob and Esau.(6) When Esau saw that Isaac had blessed Jacob and sent him off to Paddan-aram to take a wife from there, charging him, as he blessed him, “You shall not take a wife from among the Canaanite women,”(7) and that Jacob had obeyed his father and mother and gone to Paddan-aram,(8) Esau realized that the Canaanite women displeased his father Isaac.(9) So Esau went to Ishmael and took to wife, in addition to the wives he had, Mahalath the daughter of Ishmael son of Abraham, sister of Nebaioth.
Esav marries Yishmael's daughter. What does that say about him?
Rashbam:
Esav said to himself: It is because I have married Canaanite women that Yaakov was able to steal Avraham's blessing from me.
Rabbi Avraham Ben Harambam:
Even though Esav obeyed his father's wishes and married a woman who was not a Canaanite, he nevertheless did not honor Yitzhak's desire that he divorce the Canaanite wives he already had, even though he knew that his father disapproved of them.
Haamek Davar:
Yitzhak did not explicitly instruct Esav to do this. And yet the son followed Yaakov's example by fulfilling his father's will without being directly commanded to do so.
