Genesis 26:35 Meaning and Commentary

Genesis 26:35

Which were a grief of mind unto Isaac, and to Rebekah.
] The marriage of them itself was a trouble to them, it being contrary to their will that any of their children should marry with the Canaanites, and those the worst sort of them, the Hittites; it having been the care of Abraham, the father of Isaac, that his son should not marry with them, and laid a strict injunction on his servant not to take a wife for his son from among them; and which was an example to be followed in later times, and which Esau very likely was not ignorant of: and besides this, the women themselves he took for wives were very disagreeable on all accounts, partly because of their religion, being idolaters, and partly by reason of their temper and behaviour, being proud, haughty, and disobedient; as all the three Targums intimate.
