Numbers 4:4

The service of the Kohathites at the tabernacle is (relates to) "the most holy" (see at Exo 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 (Num 4:5-15). First of all (Num 4:5, Num 4:6), Aaron and his sons were to take down the curtain between the holy place and the most holy (see Exo 26:31), and to cover the ark of testimony with it (Exo 25:10). Over this they were to place a wrapper of sea-cow skin (tachash, see Exo 25:5), and over this again another covering of cloth made entirely of hyacinth-coloured purple (as in Exo 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 (Exo 25:15), but had necessarily to be taken out while it was being covered and wrapped up.

In the former chapter an account was taken of the whole tribe of Levi, in this we have an account of those of that tribe who were in the prime of their time for service, betwixt thirty and fifty years old. I. The serviceable men of the Kohathites are ordered to be numbered, and their charges are given them (v. 2-20). II. Of the Gershonites (Num 4:24-28). III. Of the Merarites (Num 4:29-33). IV. The numbers of each, and the sum total at last, are recorded (Num 4:34, etc.).

4:4-20 The duties of the Kohathites (see 3:27-32) are listed first because they performed a special service related to the most sacred objects (perhaps because Aaron and the priests came from this clan; 1 Chr 6:2-3). The tasks of carrying, setting up, and disassembling these sacred coverings and furnishings were extremely important. All the things entrusted to Kohath’s descendants—the Ark of the Covenant, the table of the Bread of the Presence, the lampstand (Hebrew menorah), the gold incense altar, and the altar for sacrifices—held tremendous value. These objects are first described in Exod 25–30, but Numbers shows how they were integrated into Hebrew life. The Kohathites carried these items on poles or in frames, and they were not to touch them or enter the sanctuary to look at them on penalty of death.
