²⁰ Moses and Aaron and all the people of Israel did this to the Levites. The people of Israel did to them all the things the Lord had told Moses about the Levites. ²¹ The Levites made themselves pure, putting away their sin. And they washed their clothes. Aaron gave them as a wave gift before the Lord. He did what had to be done to pay for their sin so they would be clean. ²² After that the Levites went in to do their work in the meeting tent in front of Aaron and his sons. So they did to the Levites just what the Lord had told Moses to do.
