Barnes' Notes on the Whole Bible

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.

wholly of blue - Compare Exodus 25:4 note. The third and external covering of the ark only was to be of this color. The table of showbread had Numbers 4:8 an outer wrapping of scarlet; the altar Numbers 4:13 one of purple.

Put in the staves - Probably, “put the staves in order.” These were never taken out of the golden rings by which the ark was to be borne (see Exodus 25:14-15), but would need adjustment.

to see when the holy things are covered - Render: to see the holy things for an instant. The expression means Iiterally” as a gulp,” i. e. for the instant it takes to swallow.

enter in to perform the service - literally, as in the margin, “to war the warfare,” or, as the same phrase in part is rendered, Numbers 4:3, “enter into the host to do the work.” The language is military. The service of God is a sacred warfare (Numbers 8:24-25 marginal reading).

By name ye shall reckon the instruments - Or, assign them to their bearers singly, and “by name.” These “instruments” comprised the heavier parts of the tabernacle; and the order seems intended to prevent individual Merarites choosing their own burden, and so throwing more than the proper share on others.
