1. The priests the Levites . . . shall eat the offerings—As the tribe of Levi had no inheritance allotted them like the other tribes but were wholly consecrated to the priestly office, their maintenance was to arise from tithes, first-fruits, and certain portions of the oblations presented on the altar, which God having by express appointment reserved to Himself made over, after being offered, to His ministers.

     3. this shall be the priest's due from the people—All who offered sacrifices of thanksgiving or peace offerings (Le 7:31-33) were ordered to give the breast and shoulder as perquisites to the priests. Here "the two cheeks" or head and "the maw" or stomach, deemed anciently a great dainty, are specified. But whether this is a new injunction, or a repetition of the old with the supplement of more details, it is not easy to determine.

     6-8. if a Levite . . . come with all the desire of his mind—It appears that the Levites served in rotation from the earliest times; but, from their great numbers, it was only at infrequent intervals they could be called into actual service. Should any Levite, however, under the influence of eminent piety, resolve to devote himself wholly and continually to the sacred duties of the sanctuary, he was allowed to realize his ardent wishes; and as he was admitted to a share of the work, so also to a share of the remuneration. Though he might have private property, that was to form no ground for withholding or even diminishing his claim to maintenance like the other ministering priests. The reason or principle of the enactment is obvious (1Co 9:13). At the same time, while every facility was afforded for the admission of such a zealous and self-denying officer, this admission was to be in an orderly manner: he was to minister "as all his brethren"—that is, a Gershonite with Gershonites; a Merarite with Merarites; so that there might be no derangement of the established courses.
