²² And after that, the Levites went 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 they did to them.

²⁴ “This also pertains to the Levites: from twenty-five years old and upward they shall go in to execute their office in the service of the Tabernacle of the Congregation.
