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 prohibited from touching the Holy Ark, much less carrying it.
Ibn Ezra
the Levites Scripture employs brevity, as if it had specified, from among the abovementioned Levites, those who are kohanim — but not all of the Levites, since the latter may not touch the Ark.
