This shall be the service of the sons of Kohath. He assigns their various offices to the Levites: firstly, lest their promiscuous sedulity should beget confusion; secondly, lest ambition should stimulate certain of them, from whence disputes and contentions might arise. We know how confusedly men work unless a certain rule is prescribed to them, lest they should run about in an aimless hurry; and whilst each individual desires to anticipate others, an unworthy emulation ensues, which afterwards vents itself in quarrels. If, therefore, this had not been prevented, the Levites would soon have made disturbances in their duty, and contentions would have taken place between them. God, then, comes forward, and by His own authority confines them all within their proper bounds, and restrains their foolish passions. That a more honorable office is assigned to the sons of Kohath than to the others, proceeds from God's gratuitous favor; and thus all pride was suppressed, lest any should boast of his dexterity, or industry, or other gifts. The charge of the Holy of holies is, therefore, entrusted to the sons of Kohath; not that they should handle any part of it, but only that they should carry on the march its vessels, when packed by the priests; for God commands the sons of Aaron to come and take down the sanctuary, and carefully cover the veil, the altar, and other sacred vessels with their proper covers, before the sons of Kohath laid a finger upon them, that thus the reverence of the people for holy things might be increased; and besides, that when the other tribes should see even the Levites forbidden from touching the sanctuary, they might be reminded of their unworthiness and humbled the more. Moreover, all cause of envy was removed when the other Levites heard that a perilous duty was entrusted to the sons of Kohath, for God threatens them with death if they touch any forbidden thing: and lastly, admonishes the priests, the sons of Aaron, lest by their carelessness they should destroy their brethren; for, if they should leave anything uncovered, they would be the cause of their destruction.

About the most holy things - Omit "about." The sense is, "this is the charge of the sons of Kohath, the most holy things:" i. e. the ark of the covenant, the table of showbread, the candlestick, and the golden altar, together with the furniture pertaining thereto. It appears, from a comparison of Numbers 4:16, Numbers 4:28, Numbers 4:33, that the ministry of the Kohathites was superintended by Eleazar, the older of the two surviving sons of Aaron; and that of the two other families by Ithamar.

This shall be the service of the sons of Kohath, in the tabernacle of the congregation,.... What follows, Numbers 4:4,
about the most holy things; which Aben Ezra interprets only of the ark, which was indeed a most holy thing, and stood in the most holy place; but there were other holy things, in the care of which the service of the Kohathites lay; as the shewbread table, the candlestick, and the altars of incense and burnt offering, and the vail, and the ministering: vessels, which Jarchi reckons with it, as more holy than all other things.

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.

This shall be the service of the sons of Kohath, &c.--They are mentioned first, from their close connection with Aaron; and the special department of duty assigned to them during the journeyings of Israel accorded with the charge they had received of the precious contents of the tabernacle. But these were to be previously covered by the common priests, who, as well as the high priest, were admitted on such necessary occasions into the holy place. This was an exception to the general rule, which prohibited the entrance of any but the high priest. But when the cloud removed from the tabernacle, the sanctuary might be entered by the common priests, as to them was reserved the exclusive privilege of packing the sacred utensils; and it was not till the holy things were thus ready for carriage, that the Kohathites were allowed to approach.

The service of the Kohathites at the tabernacle is (relates to) "the most holy" (see at Exodus 30:10). This term includes, as is afterwards explained, the most holy things in the tabernacle, viz., the ark of the covenant, the table of shew-bread, the candlestick, the altar of incense and altar of burnt-offering, together with all the other things belonging to these. When the camp was broken up, the priests were to roll them up in wrappers, and hand them over in this state to the Kohathites, for them to carry (Numbers 4:5-15). First of all (Numbers 4:5, Numbers 4:6), Aaron and his sons were to take down the curtain between the holy place and the most holy (see Exodus 26:31), and to cover the ark of testimony with it (Exodus 25:10). Over this they were to place a wrapper of sea-cow skin (tachash, see Exodus 25:5), and over this again another covering of cloth made entirely of hyacinth-coloured purple (as in Exodus 28:31). The sea-cow skin as to protect the inner curtain, which was covered over the ark, from storm and rain; the hyacinth purple, to distinguish the ark of the covenant as the throne of the glory of Jehovah. Lastly, they were to place the staves into the rings again, that is to say, the bearing poles, which were always left in their places on the ark (Exodus 25:15), but had necessarily to be taken out while it was being covered and wrapped up.
