Numbers 18:1

The Official Duties and Rights of the Priests and Levites. - Num 18:1. To impress upon the minds of the priests and Levites the holiness and responsibility of their office, the service of Aaron, of his sons, and of his father's house, i.e., of the family of the Kohathites, is described as "bearing the iniquity of the sanctuary," and the service which was peculiar to the Aaronides, as "bearing the iniquity of their priesthood." "To bear the iniquity of the sanctuary" signifies not only "to have to make expiation for all that offended against the laws of the priests and the holy things, i.e., the desecration of these" (Knobel), but "iniquity or transgression at the sanctuary," i.e., the defilement of it by the sin of those who drew near to the sanctuary; not only of the priests and Levites, but of the whole people who defiled the sanctuary in the midst of them with its holy vessels, not only by their sins (Lev 16:6), but even by their holy gifts (Exo 28:38), and thus brought guilt upon the whole congregation, which the priests were to bear, i.e., to take upon themselves and expunge, by virtue of the holiness and sanctifying power communicated to their office (see at Exo 28:38). The "iniquity of the priesthood," however, not only embraced every offence against the priesthood, every neglect of the most scrupulous and conscientious fulfilment of duty in connection with their office, but extended to all the sin which attached to the official acts of the priests, on account of the sinfulness of their nature. It was to wipe out these sins and defilements, that the annual expiation of the holy things on the day of atonement had been appointed (Lev 16:16.). The father's house of Aaron, i.e., the Levitical family of Kohath, was also to join in bearing the iniquity of the sanctuary…

The coherence of this chapter with that foregoing is very observable. I. The people, in the close of that chapter, had complained of the difficulty and peril that there were in drawing near to God, which put them under some dreadful apprehensions that the tabernacle in the midst of them, which they hoped would have been their joy and glory, would rather be their terror and ruin. Now, in answer to this complaint, God here gives them to understand by Aaron that the priests should come near for them as their representatives; so that, though the people were obliged to keep their distance, yet that should not at all redound to their disgrace or prejudice, but their comfortable communion with God should be kept up by the interposition of the priests. II. A great deal of honour God had now lately put upon Aaron; his rod had budded and blossomed, when the rods of the rest of the princes remained dry, and destitute both of fruit and ornament. Now lest Aaron should be puffed up with the abundance of the favours that were done him, and the miracles that were wrought for the support of him in his high station, God comes to him to remind him of the burden that was laid upon him, and the duty required from him as a priest. He would see reason not to be proud of his preferment, but to receive the honours of his office with reverence and holy trembling, when he considered how great was the charge committed to him, and how hard it would be for him to give a good account of it. Be not high-minded, but fear. 1. God tells him of the danger that attended his dignity, Num 18:1. (1.) That both the priests and Levites (thou, and thy sons, and thy father's house) should bear the iniquity of the sanctuary; that is, if the sanctuary were profaned by the intrusion of strangers, or persons in their…

18:1-32 The instructions given here arose from the need demonstrated in ch 17 for clear boundaries between the people and the priests and Levites. The distinctive privileges of the Levites were matched by significant responsibilities. One very important aspect of their work was to safeguard the Tabernacle from unauthorized entry (ch 16). 18:1-4 The Lord gave special authority to Aaron, his sons (the priests), and his relatives (the Levites), all of whom were held responsible for offenses against the sanctuary. But the priests alone were held responsible for their own violations of God’s instructions for their service.
