Numbers 8:7-9

New Catholic Bible

⁷ Do the following to purify them: Sprinkle the water of expiation upon them, and have them shave their entire body and wash their clothes. This will purify them. ⁸ Let them take a young bull and its cereal offering of fine flour mixed with oil. You shall also take another young bull for a sin offering. ⁹ You shall present the Levites before the tent of meeting. You shall also gather together the whole assembly of the people of Israel.
