Genesis 28:15 - If God said it, He'll do it!

And, behold, I am with thee, and will keep thee in all places whither thou goest, and will bring thee again into this land; for I will not leave thee, until I have done that which I have spoken to thee of.

Just as God said, He brought Jacob back to Luz, the Canaanite city that Jacob renamed Bethel (Genesis 28:19). Jacob returned to where he had the dream and called it Elbethel because there God appeared to him after he had fled from his brother (Genesis 35:7).

Genesis 28:4 - Jacob inherits the blessing of Abraham

And give thee the blessing of Abraham, to thee, and to thy seed with thee; that thou mayest inherit the land wherein thou art a stranger, which God gave unto Abraham.

The blessing of Abraham is to make his name great by multiplying his seed into a large and great nation and by obtaining its own land possession (Genesis 12:2; 22:17).

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).
