Numbers 7:8-10

Amplified Bible

⁸ and he gave four carts and eight oxen to the sons of Merari, according to their service [in transporting the tabernacle], under the supervision of Ithamar the son of Aaron, the [high] priest. ⁹ But to the sons of Kohath he gave nothing, because they were assigned the care of the holy things which they carried on their shoulders [when the tabernacle was moved].

¹⁰ The leaders offered the dedication sacrifices for the altar on the day that it was anointed; and they offered their sacrifice before the altar.
