Numbers 7:4-9 - The Distribution Of The Gifts
5 Take them of them, so shall they be for doing the laborious work of the ten of meeting, - and thou shalt give them unto the Levites, to every man according to the need of his laborious work.
6 So Moses took the waggons, and the oxen, - and gave them unto the Levites: 7 two of the waggons and four of the oxen, gave he unto the sons of Gershon, - according to the need of their laborious work; 8 and four of the waggons, and eight of the oxen, gave he unto the sons of Merari, - according to the need of their laborious work, in the hand of Ithamar son of Aaron the priest; 9 but, unto the sons of Kohath, gave he none, - because as to the laborious work of the sanctuary which pertained unto them, upon their shoulders, were they to carry it.
