21 The Levites made themselves clean and washed their clothes. Then Aaron presented them as an offering to the Lord. Aaron also removed their sins so they would be pure for the Lord.
22 After that, the Levites came to the Meeting Tent to work. Aaron and his sons told them what to do. They did with the Levites what the Lord commanded Moses.
23 The Lord said to Moses,
24 “This command is for the Levites. Every man 25 years old or older must come to the Meeting Tent. They all have a job to do in the work there.
25 At the age of 50, he must retire from his job. He doesn’t have to work again.
26 He may help his fellow Levites with their work at the Meeting Tent. But he must not do the work himself. This is the way you are to give the Levites their jobs.”
