Y dijo Rebeca á Isaac: Fastidio tengo de mi vida, á causa de las hijas de Heth. Si Jacob toma mujer de las hijas de Heth, como éstas, de las hijas de esta tierra, ¿para qué quiero la vida?

I am disgusted. In addition to distancing Yaakov from Eisov, this ploy would also confer on him the merit of honoring his parents.

אם לוקח יעקב אשה מבנות חת, “if Yaakov were to take a wife from amongst the Hittites;” She said this only in order to insure that Yaakov would be physically out of reach to Esau. [She could not imagine that Yaakov actually would do such a thing. Ed.] She wanted Yitzchok to specifically warn Yaakov not to marry a Hittite woman. She was afraid that unless specifically instructed, he would not want to leave his home and appear like a fugitive. He might instead marry someone from a powerful family and take his chances that they would protect him against his brother.
