20. So Moses, Aaron, and all the Israelites obeyed the Lord. They did with the Levites everything that the Lord commanded Moses.
21. The Levites washed themselves and their clothes. Then Aaron gave them to the Lord as special offerings. Aaron gave the offerings that covered their sins and made them pure.
22. After that the Levites came to the Meeting Tent to do their work. Aaron and his sons watched them. They were responsible for the work of the Levites. Aaron and his sons did what the Lord commanded Moses.
23. Then the Lord said to Moses,
24. “This is a special command for the Levites: Every Levite man who is 25 years old or older must come and share in the work at the Meeting Tent.
25. But when a man is 50 years old, he will retire from this hard work.
