Numbers 7:4-9 - The Distribution Of The Gifts
4 And the LORD spoke unto Moses, saying, 5 Take it from them, that they may be used in doing the service of the tabernacle of meeting; and you shall 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 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 them upon their shoulders.
