Numbers 8:20-22

Amplified Bible, Classic Edition

²⁰ So Moses and Aaron and all the congregation of the Israelites did thus to the Levites; according to all that the Lord commanded Moses concerning [them], so did the Israelites to them.

²¹ The Levites cleansed and purified themselves and they washed their clothes; and Aaron offered them as a wave offering before the Lord and Aaron made atonement for them to cleanse them.

²² And after that the Levites went in to do their service in the Tent of Meeting with the attendance of Aaron and his sons; as the Lord had commanded Moses concerning the Levites, so did they to them.
