This chapter gives an account of the distinct work and service of the priests and Levites, Nu 18:1-7; and of several things given to the priests for their maintenance, Nu 18:8-19; and of the tithes the Levites should have to live upon, since they were to have no inheritance in the land of Israel, Nu 18:20-24; and of the tenth out of those tithes they were to give to the high priest, Nu 18:25-32.
