Shem died in Year 2158, one hundred ten years into Yitzchak's life and fifty years into Yaakov's life [(see Chiddushei Batach, Sof Perek HaMegillah). And in Rashi on Sotah (10 71a) sixty years into Yaakov's life is a typographical error. And in Shesach 34 and in Ayin by the Rif, sixty years for Yaakov, this is also a typographical error; it seems fifty years for Yaakov. And Yaakov was already one hundred twenty years old, typographical error; it seems Yitzchak was one hundred ten years old.

And in the Midrash Bereishit section 42 and section 110, Yaakov saw Shem for fifty-eight years. And in Rashba"n chapter 50 (221b) it says twenty years. And in Ayin by the Rif, twenty years was printed, typographical error; it seems fifty years. And he saw twelve generations.

Three on one side saw twenty-two generations: Adam, Metushelach, Shem. In the Midrash Shem served Metushelach for ninety-eight years, typographical error; it seems sixty-eight. And in Rashba"n Chapter 2 (there), Chanoch buried Adam and Shem, typographical error, for Shem was born after the death of Chanoch, and look again at this, it is not Tanakh, and if you correct Shem, I am glad.] In the land of Og I saw a grave eighty cubits long, and they say it is of Shem son of Noach [(Benjamin of Tudela)].

And when Shem died, Yaakov returned to his father in Chevron.
