Ulangan 34:6

34:6 He ¹  buried him in the land of Moab near Beth Peor, but no one knows his exact burial place to this very day.

[34:6]  ¹ tc Smr and some LXX mss read “they buried him,” that is, the Israelites. The MT reads “he buried him,” meaning in the context that “the Lord buried him.” This understanding, combined with the statement at the end of the verse that Moses’ burial place is unknown, gave rise to traditions during the intertestamental period that are reflected in the NT in Jude 9 and in OT pseudepigraphic works like the Assumption of Moses.
