Numbers 8:20-22 Douay-Rheims 1899 American Edition (DRA)
20 And Moses and Aaron and all the multitude of the children of Israel did with the Levites all that the Lord had commanded Moses:
21 And they were purified, and washed their garments. And Aaron lifted them up in the sight of the Lord, and prayed for them,
22 That being purified they might go into the tabernacle of the covenant to do their services before Aaron and his sons. As the Lord had commanded Moses touching the Levites, so was it done.
