Numbers 8:7-9

New Century Version

⁷ 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. ⁸ They must take a young bull and the grain offering of flour mixed with oil that goes with it. Then take a second young bull for a sin offering. ⁹ Bring the Levites to the front of the Meeting Tent, and gather all the Israelites around.
