21. The Levites performed the ceremonies to take away their sins and washed their clothes. Aaron presented them as an offering to the Lord and made peace with the Lord for them in order to make them clean.
22. After that, the Levites came and did their work at the tent of meeting in the presence of Aaron and his sons. They did as the Lord had commanded Moses.
23. The Lord said to Moses,
24. “These are the instructions for the Levites: Men 25 years old or older are eligible to serve at the tent of meeting.
25. But when they’re 50 years old, they must retire from active service and not work anymore.
26. They may assist the other Levites in their duties at the tent of meeting, but they may not do any regular work. This is how you will handle the Levites’ duties.”
