Numbers 8:22

And afterwards the Levites went in to minister in their service in the tabernacle of witness before Aaron, and before his sons; as the Lord appointed Moses concerning the Levites, so they did to them.

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.

After that, the Levites went in to do their service in the Tent of Meeting before Aaron and before his sons: as Yahweh had commanded Moses concerning the Levites, so they did to them.
