Numbers 8:11-13

VIN(i) 11 "Aaron will present the Levites to the LORD as an offering from the Israelites. Then they will be ready to do the LORD’s work. 12 And the Levites shall lay their hands upon the heads of the bullocks, and offer thou the one for a sin-offering, and the other for a burnt-offering, to LORD, to make atonement for the Levites. 13 "Make the Levites stand in front of Aaron and his sons, and present them as an offering to the LORD.
