16 For they are completely given unto me from among the sons of Israel, instead of each one that opens the womb; instead of the firstborn of all the sons of Israel, I have taken them for myself.
17 For all the firstborn of the sons of Israel are mine, both of man and of animals; from the day that I smote every firstborn in the land of Egypt I sanctified them for myself.
18 And I have taken the Levites for all the firstborn of the sons of Israel.
19 And I have given the Levites as a gift to Aaron and to his sons from among the sons of Israel, that they may serve the ministry of the sons of Israel in the tabernacle of the testimony and reconcile the sons of Israel, that there be no plague in the sons of Israel when the sons of Israel come near unto the sanctuary.
20 And Moses and Aaron and all the congregation of the sons of Israel did to the Levites according unto all that the Lord commanded Moses concerning the Levites, so did the sons of Israel unto them.
21 And the sin was removed from the Levites, and they washed their clothes; and Aaron offered them for a wave offering before the Lord; and Aaron reconciled them to cleanse them.
22 And thus went the Levites in to serve in their ministry in the tabernacle of the testimony before Aaron and before his sons; in the manner that the Lord had commanded Moses concerning the Levites, so did they unto them.
