9 And you shall bring the Levites before the tabernacle of meeting: and you shall gather the whole assembly of the children of Israel together:
10 And you shall bring the Levites before the LORD: and the children of Israel shall put their hands upon the Levites:
11 And Aaron shall offer the Levites before the LORD for an offering of the children of Israel, that they may execute the service of the LORD.
12 And the Levites shall lay their hands upon the heads of the bullocks: and you shall offer the one for a sin offering, and the other for a burnt offering, unto the LORD, to make an atonement for the Levites.
13 And you shall set the Levites before Aaron, and before his sons, and offer them for an offering unto the LORD.
14 Thus shall you separate the Levites from among the children of Israel: and the Levites shall be mine.
15 And after that shall the Levites go in to do the service of the tabernacle of meeting: and you shall cleanse them, and offer them for an offering.
