Числа 18:5

Service and Revenues of the Priests and Levites - Numbers 18 The practical confirmation of the priesthood of Aaron and his family, on the part of God, is very appropriately followed by the legal regulations concerning the official duties of the priest and Levites (Num 18:1-7), and the revenues to be assigned them for their services (vv. 8-32), as the laws hitherto given upon this subject, although they contain many isolated stipulations, have not laid down any complete and comprehensive arrangement. The instructions relating to this subject were addressed by Jehovah directly to Aaron (see Num 18:1 and Num 18:8), up to the law, that out of the tenths which the Levites were to collect from the people, they were to pay a tenth again to the priests; and this was addressed to Moses (Num 18:25), as the head of all Israel.

Aaron being now fully established in the priesthood abundantly to his own satisfaction, and to the satisfaction of the people (which was the good that God brought out of the evil opposition made to him), in this chapter God gives him full instructions concerning his office or rather repeats those which he had before given him. He tells him, I. What must be his work and the care and charge committed to him, and what assistance he should have the Levites in that work (Num 18:1-7). II. What should be his and the Levites' wages for this work. 1. The perquisites or fees peculiar to the priests (Num 18:8-19). 2. The settled maintenance of the Levites (Num 18:20-24). III. The portion which must be paid to the priests out of the Levites' maintenance (Num 18:25-32). Thus every one knew what he had to do, and what he had to live upon.

18:5-7 Only the priests (Aaron and his descendants) could perform sacred duties inside the sanctuary proper or approach the altar, a sacred space that deserved special reverence. Only the high priest could serve in the Most Holy Place. The Levites were to serve only in the courtyard, away from the altar, except when it was time to assemble or disassemble the Tabernacle (ch 4). 18:5 Aaron and the priests were the people’s representatives before the Lord, so their actions had consequences for all of Israel (cp. 16:18-21).
