Numbers 8:6

2 “Speak to Aaron and tell him: ‘When you set up the seven lamps, they are to light the area in front of the lampstand.’”

3 And Aaron did so; he set up the lamps facing toward the front of the lampstand, just as the LORD had commanded Moses.

4 This is how the lampstand was constructed: it was made of hammered gold from its base to its blossoms, fashioned according to the pattern the LORD had shown Moses.

5 Again the LORD spoke to Moses, saying,

6 “Take the Levites from among the Israelites and make them ceremonially clean.

7 This is what you must do to cleanse them: Sprinkle them with the water of purification. Have them shave their whole bodies and wash their clothes, and so purify themselves.

8 Then have them take a young bull with its grain offering of fine flour mixed with oil, and you are to take a second young bull for a sin offering.

9 Bring the Levites before the Tent of Meeting and assemble the whole congregation of Israel.

10 You are to present the Levites before the LORD and have the Israelites lay their hands upon them.
