Numbers 7:4-9 - The Distribution Of The Gifts
4 And the LORD spoke unto Moses, saying, 5 Take it from them, and it shall be for the service of the tabernacle of the testimony; and thou shalt give them unto the Levites, to each one according to his ministry.
6 Then Moses received 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 ministry; 8 and four wagons and eight oxen he gave unto the sons of Merari, according to their ministry, under the hand of Ithamar, the son of Aaron the priest. 9 But unto the sons of Kohath he gave none; because the ministry of the sanctuary belonging unto them was that they should bear upon their shoulders.
