Numbers 8:22-26 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.

Brenton⁽ⁱ⁾ 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. ²³ And the Lord spoke to Moses, saying, ²⁴ This is the ordinance for the Levites; From five and twenty years old and upward, they shall go in to minister in the tabernacle of witness. ²⁵ And from fifty years old the Levites shall cease from the ministry, and shall not work any longer. ²⁶ And his brother shall serve in the tabernacle of witness to keep charges, but he shall not do works: so shalt thou do to the Levites in their charges.
