21. The Levites purified themselves and washed their clothes. Aaron presented them as an uplifted offering in the Lord’s presence, and he sought reconciliation for them in order to cleanse them.
22. After this the Levites went in to perform their service in the meeting tent before Aaron and his sons. They did for the Levites just as the Lord had commanded Moses concerning them.
23. The Lord spoke to Moses:
24. This rule applies to the Levites: Everyone 25 years old and above will enter into service, performing the duties for the meeting tent.
25. At 50 years old each will retire from service. They will perform their duties no longer.
26. Each may assist his fellow Levites in the meeting tent with some responsibilities, but he may not perform service. This is how you should assign responsibilities to the Levites.
