Genesis 27:46 - More chicanery by Rebekah.

And Rebekah said to Isaac, I am weary of my life because of the daughters of Heth: if Jacob take a wife of the daughters of Heth, such as these which are of the daughters of the land, what good shall my life do me?

Rebekah is trying to get Isaac to support her idea of having Jacob flee to her homeland in Padanaram (Genesis 27:43). Esau already grieved Isaac by marrying Hittite women (Genesis 26:34, 35) so Rebekah is hoping that Isaac will advise Jacob to follow his own footsteps in finding a wife in Padanaram (Genesis 25:20).
