Jacob, nearing his death, begins to bless his sons. Jacob claims Joseph's Egyptian-born sons as his own, incorporating them into his heritage. This doubles Joseph's tribal allotment. Jacob also blesses Ephraim, the secondborn, more than Manasseh, the firstborn. Jacob also gives Joseph a mountain slope, and all the blessings on Joseph's children will be remembered in Heb 11:21.
Jacob remembers Reuben as powerful and unruly, and because he took up with Bilhah, he is no longer given preeminence. Simeon and Levi are divided, and their tribes will be scattered, because they are weapons of violence. Levi is not given a region in the tribal allotment, and Simeon is given a region entirely surrounded by Judah.
Judah will be praised, and rulers will come from him, and we look to the eventual coming of Christ through this. Zebulun is given the crossroads from the trade coming over the sea. Issachar is also given an area of trade, but will have to labor for it. Dan is given his portion, but will eventually be dispossessed from it. Joseph is given many blessings.
After all of this, Jacob dies.
