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, 2Co 5:1, and the putting it off, 2Pe 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.At the appointment of Aaron and his sons,.... As they shall order and direct:

shall be all the service of the sons of the Gershonites; everyone of them was to take their share, as Aaron and his sons should appoint them:

in all their burdens, and in all their service; what each of them should carry, and in what they should perform duty:

and ye shall appoint to them in charge all their burdens; charge them carefully to keep all that were committed to them to bear, that none be lost, not a pin nor a cord.
