Numbers 7
4 And the LORD spake unto Moses, saying,
5 Ref Take it of them, that they may be to do the service of the tabernacle of the congregation; and thou shalt give them unto the Levites, to every man according to his service.
6 And Moses took the wagons and the oxen, and gave them unto the Levites.
7 Ref Two wagons and four oxen he gave unto the sons of Gershon, according to their service:
8 Ref 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 Ref 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.
