Numbers 7:7 WEB

⁵  'Accept these from them, that they may be used in doing the service of the Tent of Meeting; and you shall give them to the Levites, to every man according to his service.'

⁶  Moses took the wagons and the oxen, and gave them to the Levites.

⁷  He gave two wagons and four oxen to the sons of Gershon, according to their service:

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

⁹  But to the sons of Kohath he gave none, because the service of the sanctuary belonged to them; they carried it on their shoulders.
