18 "Do not cut off the tribe of the families of the Kohathites from among the Levites; 19 but do this in regard to them, that they may live and not die when they approach the most holy things: Aaron and his sons shall go in and appoint each of them to his service and his task. 20 But they shall not go in to watch while the holy things are being covered, lest they die."
21 Then the Lord spoke to Moses, saying: 22 "Also take a census of the sons of Gershon, by their fathers' house, by their families.

Commentary on Numbers 4:4-20
(Read Numbers 4:4-20)
The Kohathites were to carry the holy things of the tabernacle. All the holy things were to be covered; not only for security and respect, but to keep them from being seen. This not only marked the reverence due to holy things, but the mystery of the things signified by those types, and the darkness of the dispensation. But now, through Christ, the case is altered, and we are encouraged to come boldly to the throne of grace.
Commentary on Numbers 4:21-33
(Read Numbers 4:21-33)
We have here the charge of the other two families of the Levites, which, though not so honourable as the first, yet was necessary, and to be done regularly. All the things were delivered them by name. It intimates the care God takes of his church and every member of it. The death of the saints is represented as the taking down of the tabernacle, 2 Peter 1:14. All shall be raised up in the great day, when these vile bodies shall be made like the glorious body of Jesus Christ, and so shall be for ever with the Lord.
