Verse 4. - About the most holy things. Rather, "the most holy things:" they were the service of the Kohathites. So the Septuagint.

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.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.
