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