Deu 18:1-8. The Lord is the Priests’ and Levites’ inheritance.
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.
