Jacob calls his sons to him before he dies to bless them and prophesy about their future descendants. He rebukes Reuben for defiling his father's bed and says his birthright will be given to Joseph. Jacob says Judah's brothers will praise him and bow down to him, and that a ruler will come from Judah. Jacob also blesses Zebulun, Issachar, Dan, Gad, Asher, Naphtali and Joseph with prophecies about the character and roles of their future tribes.
