Numbers 8:6

⁴  And this work of the candlestick was of beaten gold, unto the shaft thereof, unto the flowers thereof, was beaten work: according unto the pattern which the LORD had showed Moses, so he made the candlestick.

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.

⁸  Then let them take a young bullock with his meat offering, even fine flour mingled with oil, and another young bullock shalt thou take for a sin offering.
