15 And when Aaron and his sons have finished covering the sanctuary and all the furnishings of the sanctuary, when the camp is set to go, then the sons of Kohath shall come to carry them; but they shall not touch any holy thing, lest they die. These are the things in the tabernacle of meeting which the sons of Kohath are to carry.
Matthew Henry's Commentary on Numbers 4:15
Commentary on Numbers 4:4-20
(Read Numbers 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.
