Numbers 8:20-22

New International Reader's Version

²⁰ So Moses and Aaron and all the Israelites did with the Levites just as the Lord had commanded Moses. ²¹ The Levites made themselves pure. They washed their clothes. Then Aaron gave them to the Lord as a wave offering. That’s how he paid for their sin to make them pure. ²² After that, the Levites came to do their work at the tent of meeting. They worked under the direction of Aaron and his sons. And so Moses and Aaron and the whole community of Israel did with the Levites just as the Lord had commanded Moses.
