Numbers 8:22-26

The Message

^20-22 Moses, Aaron, and the entire community of the People of Israel carried out these procedures with the Levites, just as God had commanded Moses. The Levites purified themselves and scrubbed their clothes. Then Aaron presented them as a Wave-Offering before God and made atonement for them to purify them. Only then did the Levites go to work at the Tent of Meeting. Aaron and his sons supervised them following the directions God had given.

^23-26 God spoke to Moses: “These are your instructions regarding the Levites: At the age of twenty-five they will join the workforce in the Tent of Meeting; at the age of fifty they must retire from the work. They can assist their brothers in the tasks in the Tent of Meeting, but they are not permitted to do the actual work themselves. These are the ground rules for the work of the Levites.”
