⁸  Then let them take a young bullock with his meat-offering, [even] fine flour mingled with oil, and another young bullock shalt thou take for a sin-offering.

⁹  And thou shalt bring the Levites before the tabernacle of the congregation: and thou shalt convene the whole assembly of the children of Israel:

¹⁰  And thou shalt 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 thou shalt offer the one [for] a sin-offering, and the other [for] a burnt-offering, to the LORD, to make an atonement for the Levites.
