At the command of the Lord they camped, and at the command of the Lord they set out; they kept the Lord’s charge, according to the command of the Lord through Moses.

But the Lord said to Moses, “Put back the rod of Aaron before the testimony to be kept as a sign against the rebels, that you may put an end to their grumblings against Me, so that they will not die.”

and from the sons of Israel’s half, Moses took one drawn out of every fifty, both of man and of animals, and gave them to the Levites, who kept charge of the tabernacle of the Lord, just as the Lord had commanded Moses.
