Shall not profane the holy things— That this verse refers to the priests, and not to the people, is evident from the context, and from the following verse. Provision is made in the former verse, that the holy things appropriated to their maintenance should be exactly rendered to the priests: here it is observed, in reference to the cautions given in the former part of the chapter, that the priests themselves should not profane the holy things, by an improper and defiling use of them; and thus lade themselves with the iniquity of trespass in their eating; i.e. render themselves obnoxious to divine justice by transgressing these ordinances.
Note; There is but one Mediator, who is appointed to bear our sins, and we must be careful to join no other with him. His blood and merits alone, not any works of ours, or of others, have any efficacy in obtaining remission of the iniquity of our trespass.
