Commentary for Deuteronomy 31:25

V. 25. ויצו משה וגו׳ siehe zu S. 9.

ויצו משה את הלוים, “Moses ordered the Levites, etc.” these are the Levites who had been mentioned in verse 9 as the “priests, who were the sons of the Levites;” Moses was not addressing the tribe of the Levites here. After all, the Levites at large were not charged with touching the Holy Ark, much less carrying it.
