⁷ Two wagons and four oxen he gave to the sons of Gershon, according to their service;

⁸ And four wagons and eight oxen he gave to the sons of Merari, according to their service, under the supervision of Ithamar son of Aaron, the [high] priest.

⁹ But to the sons of Kohath he gave none, because they were assigned the care of the sanctuary and the holy things which had to be carried on their shoulders.
