Numbers 8:22
And after that went the Levites in to do their service in the tabernacle of the congregation before Aaron, and before his sons: as the LORD had commanded Moses concerning the Levites, so did they unto them.
And after that went the Levites in,.... Into the court of the tabernacle, being at the door of it when the above rites and ceremonies of their consecration were performed:
to do their service in the tabernacle of the congregation, before Aaron and his sons; in their presence, and by their order, as they should direct them:
as the LORD had commanded Moses, so did they unto them; Aaron and his sons did to the then present Levites according to the command of God by Moses; they exactly observed every punctilio of it, and complied with it; and this the sons of Aaron did continually to the sons of the Levites, as Aben Ezra remarks, in all succeeding ages; when the Levites were consecrated to their service, the same things were done unto them that are here ordered.
