4This 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.
7To 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.
8Have 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.
12"Then the Levites are to lay their hands on the heads of the bulls, using one for a sin offering to the LORD and the other for a burnt offering, to make atonement for the Levites.
16They are the Israelites who are to be given wholly to me. I have taken them as my own in place of the firstborn, the first male offspring from every Israelite woman.
19From among all the Israelites, I have given the Levites as gifts to Aaron and his sons to do the work at the tent of meeting on behalf of the Israelites and to make atonement for them so that no plague will strike the Israelites when they go near the sanctuary."
21The Levites purified themselves and washed their clothes. Then Aaron presented them as a wave offering before the LORD and made atonement for them to purify them.
22After that, the Levites came to do their work at the tent of meeting under the supervision of Aaron and his sons. They did with the Levites just as the LORD commanded Moses.
26They may assist their brothers in performing their duties at the tent of meeting, but they themselves must not do the work. This, then, is how you are to assign the responsibilities of the Levites."
