Is the Torah a Pentateuch or Hexateuch?

But where does this story of promise and fulfillment really end? At the end of the Torah with the death of Moses?

The adjuration by Joseph is only completed in Joshua, specifically in the next to last verse of that book (24:32): “The bones of Joseph, which the Israelites had brought up from Egypt, were buried at Shechem, in the piece of ground which Jacob had bought for a hundred kesitahs from the children of Hamor, Shechem’s father, and which had become a heritage of the Josephites.”[7] In fact, that final chapter of Joshua is full of references to the Torah, especially to Genesis, suggesting that Genesis-Joshua form an inclusio,[8] a device that demarcates a literary work; thus Genesis through Joshua should be viewed as a unit.
