7 And thus shalt thou do unto them, to cleanse them: Sprinkle water of atonement for sin upon them, and let them shave all their flesh, and let them wash their clothes, and be clean.
8 Then let them take a young bullock with his present, even fine flour mingled with oil, and another young bullock shalt thou offer as sin.
9 And thou shalt offer the Levites before the tabernacle of the testimony, and thou shalt gather the whole congregation of the sons of Israel together;
10 and thou shalt bring the Levites before the Lord, and the sons of Israel shall put their hands upon the Levites;
11 and Aaron shall offer the Levites before the Lord for a wave offering of the sons of Israel, and they shall serve in the ministry of the Lord.
12 And the Levites shall lay their hands upon the heads of the bullocks; and thou shalt offer the one as the sin, and the other as a burnt offering, unto the Lord, to reconcile the Levites.
13 And thou shalt cause the Levites to present themselves before Aaron, and before his sons, and offer them for an offering unto the Lord.
