Numbers 8:5-7

King James Version

⁵ And the Lord spake unto Moses, saying,

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 water of purifying upon them, and let them shave all their flesh, and let them wash their clothes, and so make themselves clean.
