Numbers 8:7-9

Darby Translation

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.

⁹ And thou shalt bring the Levites before the tent of meeting; and thou shalt gather together the whole assembly of the children of Israel.
