Numbers 8:1-9

The LORD said to Moses, “Speak to Aaron and say to him, ‘When you set up the lamps, see that all seven light up the area in front of the lampstand.’ ” Aaron did so; he set up the lamps so that they faced forward on the lampstand, just as the LORD commanded Moses. This is how the lampstand was made: It was made of hammered gold—from its base to its blossoms. The lampstand was made exactly like the pattern the LORD had shown Moses. The LORD said to Moses: “Take the Levites from among all the Israelites and make them ceremonially clean. To purify them, do this: Sprinkle the water of cleansing on them; then have them shave their whole bodies and wash their clothes. And so they will purify themselves. Have them take a young bull with its grain offering of the finest flour mixed with olive oil; then you are to take a second young bull for a sin offering. Bring the Levites to the front of the tent of meeting and assemble the whole Israelite community.
