Num 8:1-7

The Seven Lamps 1The Lord spoke to Moses, saying:2Speak to Aaron and say to him: When you set up the lamps, the seven lamps shall give light in front of the lampstand.3Aaron did so; he set up its lamps to give light in front of the lampstand, as the Lord had commanded Moses.4Now this was how the lampstand was made, out of hammered work of gold. From its base to its flowers, it was hammered work; according to the pattern that the Lord had shown Moses, so he made the lampstand.Consecration and Service of the Levites 5The Lord spoke to Moses, saying:6Take the Levites from among the Israelites and cleanse them.7Thus you shall do to them, to cleanse them: sprinkle the water of purification on them, have them shave their whole body with a razor and wash their clothes, and so cleanse themselves.
