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, unto the LORD, to make an atonement for the Levites.
The Levites will place their hands on the bulls' heads. Then, you will offer one bull as a sin offering and the other as a burnt offering to God. This is done to forgive the Levites.
