Numbers 7:7-9

King James Version

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

⁸ And four wagons and eight oxen he gave unto the sons of Merari, according unto their service, under the hand of Ithamar the son of Aaron the priest.

⁹ But unto the sons of Kohath he gave none: because the service of the sanctuary belonging unto them was that they should bear upon their shoulders.
