This website (thetorah.com) raises some points about Moshe Rabbeinu's death.
A few points that they make is:
If Moses ascends Mount Nebo in verse 1, how does he end up buried in the valley below in verse 6?
Where precisely does he meet his demise—on the mountain, in the valley, or somewhere in-between?
- How is he transported to his final repose, and by whom?
- Who is the unnamed “he” that buries Moses in verse 6?
