Numbers 8:12-14

Amplified Bible, Classic Edition

¹² Then the Levites shall lay their hands upon the heads of the bulls, and you shall offer the one for a sin offering and the other for a burnt offering to the Lord, to make atonement for the Levites.

¹³ And you shall present the Levites before Aaron and his sons and offer them as a wave offering to the Lord.

¹⁴ Thus you shall separate the Levites from among the Israelites, and the Levites shall be Mine [in a very special sense].
