He took to wife - the daughter, etc. - It is very likely that the wives taken by Esau were daughters of chiefs among the Hittites, and by this union he sought to increase and strengthen his secular power and influence.

And Esau was forty years old,.... The same age his father was of when he married, Genesis 25:20,

when he took to wife Judith, the daughter of Beeri the Hittite; Josephus (m) makes her to be the same with Aholibamah; but her father's name was Zibeon, and an Hivite, and must therefore be another person, not only the name being different, but the tribe, Genesis 36:2,

and Bashemath the daughter of Elon the Hittite; whom Aben Ezra takes to be the same with Adah, and so does Josephus; and in this they may be right, since the name of her father, and his nation or tribe, agree, Genesis 36:2. The fathers of these two women are represented by Josephus as men of great power and authority among the Canaanites, as very probably they were. Esau had another wife of the same name with this last, but she was daughter of Ishmael, and sister of Nebajoth, Genesis 36:3; for he had more wives than those; these were his two first, who very probably were not taken together, but one after another, though it may be but at a short distance from each other.

Esau's Marriage. - To the various troubles which the Philistines prepared for Isaac, but which, through the blessing of God, only contributed to the increase of his wealth and importance, a domestic cross was added, which caused him great and lasting sorrow. Esau married two wives in the 40th year of his age, the 100th of Isaac's life (Genesis 25:26); and that not from his own relations in Mesopotamia, but from among the Canaanites whom God had cast off. On their names, see Genesis 34:2-3. They became "bitterness of spirit," the cause of deep trouble, to his parents, viz., on account of their Canaanitish character, which was so opposed to the vocation of the patriarchs; whilst Esau by these marriages furnished another proof, how thoroughly his heart was set upon earthly things.

And Esau was forty years old when he took to wife Judith the daughter of Beeri the Hittite, and Bashemath the daughter of Elon the Hittite:

26:34 He took to wife - Marrying Canaanites, who were strangers to the blessing of Abraham, and subject to the curse of Noah.

34. Esau . took to wife-If the pious feelings of Abraham recoiled from the idea of Isaac forming a matrimonial connection with a Canaanitish woman [Ge 24:3], that devout patriarch himself would be equally opposed to such a union on the part of his children; and we may easily imagine how much his pious heart was wounded, and the family peace destroyed, when his favorite but wayward son brought no less than two idolatrous wives among them-an additional proof that Esau neither desired the blessing nor dreaded the curse of God. These wives never gained the affections of his parents, and this estrangement was overruled by God for keeping the chosen family aloof from the dangers of heathen influence.

26:34,35 Esau was foolish in marrying two wives together, and still more in marrying Canaanites, strangers to the blessing of Abraham, and subject to the curse of Noah. It grieved his parents that he married without their advice and consent. It grieved them that he married among those who had no religion. Children have little reason to expect God's blessing who do that which is a grief of mind to good parents.
