Numbers 8:6-8

New Century Version

⁶ “Take the Levites away from the other Israelites and make them clean. 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.
