Context Reading
5Again the LORD spoke to Moses, saying, 6“Take the Levites from among the Israelites and make them ceremonially clean. 7This is what you must do to cleanse them: Sprinkle them with the water of purification. Have them shave their whole bodies and wash their clothes, and so purify themselves. 8Then have them take a young bull with its grain offering of fine flour mixed with oil, and you are to take a second young bull for a sin offering. 9Bring the Levites before the Tent of Meeting and assemble the whole congregation of Israel.
