Numbers 8:7-9

Complete Jewish Bible

⁷ Here is how you are to cleanse them: sprinkle the purification water on them, have them shave their whole body with a razor, and have them wash their clothes and cleanse themselves. ⁸ Then they are to take a young bull with its grain offering, which is to be fine flour mixed with olive oil; while you take another bull for a sin offering. ⁹ You are to present the L’vi’im in front of the tent of meeting, and assemble the entire community of the people of Isra’el.
