Numbers 8:6-8

Darby Translation

⁶ Take the Levites from among the children of Israel, and cleanse them.

⁷ And thus shalt thou do unto them, to cleanse them: sprinkle upon them water of purification from sin; and they shall pass the razor over all their flesh, and shall wash their garments, and make themselves clean.

⁸ And they shall take a young bullock and its oblation of fine flour mingled with oil; and another young bullock shalt thou take for a sin-offering.
