The Levites made themselves clean and washed their clothes. Then Aaron presented them as an offering to the Lord. He also removed their sins so they would be pure.
They must wash themselves with the cleansing water on the third day and on the seventh day; then they will be clean. But if they do not wash themselves on the third day and the seventh day, they cannot be clean.
The person who is clean must sprinkle this water on the unclean people on the third day and on the seventh day. On the seventh day they will become clean. They must wash their clothes and take a bath, and they will be clean that evening.
After that, the Levites came to the Meeting Tent to work, and Aaron and his sons told them what to do. They did with the Levites what the Lord commanded Moses.
This is what you should do to make them clean: Sprinkle the cleansing water on them, and have them shave their bodies and wash their clothes so they will be clean.
