B'resheet 28:1-5 So Yitz'chak called Ya'akov and blessed him and charged him, and said to him, "You shall not take a wife from the daughters of Canaan. Arise, go to Paddan-aram, to the house of Bethuel your mother's father; and from there take to yourself a wife from the daughters of Laban your mother's brother. And may G-d Almighty bless you and make you fruitful and multiply you, that you may become a company of peoples. May He also give you the blessing of Abraham, to you and to your descendants with you; that you may possess the land of your sojournings, which G-d gave to Abraham." Then Yitz'chak sent Ya'akov away, and he went to Paddan-aram to Laban, son of Bethuel the Aramean, the brother of Rivkah, the mother of Ya'akov and Esav.
Why was he not to take a wife of the Canaanites? Remember the curse that was placed on Canaan by Noah?
B'resheet 9:25 "So he said, "Cursed be Canaan; a servant of servants He shall be to his brothers."
And most of the Canaanites where known for their sexual sin and perversion.
Paddan-aram - The "plain of Aram" in upper Mesopotamia near Haran. This is now modern day northeastern Iraq.
Yitz'chak realizes that the Abrahamic covenant was to pass on to Ya'akov and not to Esav. He again blesses Ya'akov with being a great nation and possessing the land of Israel.
B'resheet 28:6-9 Now Esav saw that Yitz'chak had blessed Ya'akov and sent him away to Paddan-aram, to take to himself a wife from there, and that when he blessed him he charged him, saying, "You shall not take a wife from the daughters of Canaan," and that Ya'akov had obeyed his father and his mother and had gone to Paddan-aram. So Esav saw that the daughters of Canaan displeased his father Yitz'chak; and Esav went to Yishma'el, and married, besides the wives that he had, Mahalath the daughter of Yishma'el, Abraham's son, the sister of Nebaioth.
Esav is still trying to get his fathers approval. He was already married to two Hittite women, and now he planned to take a cousin, a daughter of his uncle Yishma'el, as his wife, in order to win his father's favor.
B'resheet 28:10-17 Then Ya'akov departed from Beersheba and went toward Haran. And he came to a certain place and spent the night there, because the sun had set; and he took one of the stones of the place and put it under his head, and lay down in that place. And he had a dream, and behold, a ladder was set on the earth with its top reaching to heaven; and behold, the angels of G-d were ascending and descending on it. And behold, the L-RD stood above it and said, "I am the L-RD, the G-d of your father Abraham and the G-d of Yitz'chak; the land on which you lie, I will give it to you and to your descendants. Your descendants shall also be like the dust of the earth, and you shall spread out to the west and to the east and to the north and to the south; and in you and in your descendants shall all the families of the earth be blessed. And behold, I am with you, and will keep you wherever you go, and will bring you back to this land; for I will not leave you until I have done what I have promised you." Then Ya'akov awoke from his sleep and said, "Surely the L-RD is in this place, and I did not know it." And he was afraid and said, "How awesome is this place! This is none other than the house of G-d, and this is the gate of heaven."
It is Interesting that Vav, the Hebrew letter corresponding to this chapter, is a link between heaven and earth and can also deal with different dimensions. Vav also means hook; completion; redemption and transformation. Stands for man created on the sixth day. Etc.
Here Ya'akov dreams of a ladder between heaven and earth. What is a clue to what this latter points to?
Angels of G-d are ascending and descending on it. Where else does this kind of description happen in the Bible?
John 1:48-2:1 Nathaniel said to Him, "How do You know me?" Yeshua answered and said to him, "Before Philip called you, when you were under the fig tree, I saw you." Nathaniel answered Him, "Rabbi, You are the Son of G-d; You are the King of Israel." Yeshua answered and said to him, "Because I said to you that I saw you under the fig tree, do you believe? You shall see greater things than these." And He said to him, "Truly, truly, I say to you, you shall see the heavens opened, and THE ANGELS OF G-D ASCENDING AND DESCENDING on the SON OF MAN."
We are all blessed by following the true Jewish faith by following the Jewish Messiah, Yeshua. He was and is the only ladder that allows us to climb into the other world. If you climb another way you will not be allowed to enter.
G-d, Himself, confirms His covenant with Ya'akov.
