Moses reckoned them up according to the word of the Lord, every one according to their office and burdens, as the Lord had commanded him.

by the command of Jehovah hath one numbered them, by the hand of Moses, each man by his service, and by his burden, with his numbered ones, as Jehovah hath commanded Moses.

At the order of the Lord they were numbered by Moses, every one in relation to his work and to his part in the transport; so they were numbered by Moses at the order of the Lord.

According to the commandment of the LORD they were appointed by the hand of Moses, every one to his service, and to his burden; they were also numbered, as the LORD commanded Moses.

Moses took a census of them, according to the word of the Lord, each one according to their office and their burdens, just as the Lord had instructed him.

Juxta sermonem Jehovae numeravit cos per manum Mosis, singulos secundum ministerium suum, et secundum onus suum: numerati autem ejus fuerunt hi quos ipsi praeceperat.

According to the commandment of the LORD they were numbered by the hand of Moses, every one according to his service, and according to his burden: thus were they numbered of him, as the LORD commanded (x) Moses.
(x) So that Moses neither added, nor diminished from that which the Lord commanded him.

According to the commandment of the Lord, they were numbered by the hand of Moses,.... Aaron and the chief of the congregation of Israel assisting it:
everyone according to his service; called in Numbers 4:47 "the service of the ministry", or "service of service", which Jarchi interprets of that part of the service of the Levites, which lay in singing the song with cymbals and harps; which, he says, was a service to another service; though it seems to be better explained, by Chaskuni, of their taking down and setting up of the tabernacle, which was a service incumbent on all the Levites:
and according to his burden: called "the service of the burden", Numbers 4:47; which the last mentioned writer restrains to the ark, table, candlestick, and altars, which the Kohathites carried on their shoulders; but may be extended to what each of them bore and carried when journeying:
thus were they numbered of him, as the Lord commanded Moses; from thirty years old to fifty, as Jarchi observes; for that was the order given to Moses by the Lord, which he punctually attended to, as a faithful servant in the house of God.

"According to the commandment of Jehovah, they appointed them through the hand of Moses (i.e., under his direction), each one to his service, and his burden, and his mustered things (פּקדיו), i.e., the things assigned to him at the time of the mustering as his special charge (see Exodus 38:21).
