Numbers 7:4-9 - The Distribution Of The Gifts
4 And LORD spoke to Moses, saying, 5 Take it from them, that they may be [used] in doing the service of the tent of meeting. And thou shall give them to the Levites, to every man according to his service.
6 And Moses took the wagons and the oxen, and gave them to the Levites. 7 Two wagons and four oxen he gave 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 hand of Ithamar the son of Aaron the priest. 9 But he gave none to the sons of Kohath, because the service of the sanctuary belonged to them. They bore it upon their shoulders.
