Numbers 8:5

³  And Aaron did so; he lighted the lamps thereof over against the candlestick, as the LORD commanded Moses.

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.
