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.
So the Lord said to Moses, “Go to the people, and tell them they have two days to get ready. They must set themselves apart as holy. Have them wash their clothes
The unclean person must use this water on the third day and the seventh day to take away his sin. Then he will be clean. But if he doesn’t use this water on the third day and the seventh day, he will not be clean.
A person who is clean will sprinkle these types of unclean people on the third day and the seventh day. On the seventh day the clean person will finish taking away their sins. Then they must wash their clothes and bodies, and in the evening they will be clean.
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.
This is what you must do to make them clean: Sprinkle them with water to take away their sins. Make them shave their whole bodies and wash their clothes. Then they will be clean.
