21. The Levites sprinkled themselves with the water of forgiveness and washed their clothes. Then Aaron brought them to the altar and offered sacrifices to forgive their sins and make them acceptable to the Lord.
22. After this, the Levites worked at the sacred tent as assistants to Aaron and his sons, just as the Lord had commanded.
