Numbers 7:4-9 - The Distribution Of The Gifts
4 Yahweh said to Moses, saying, 5 "{Take them}, and they will be [used] to do the work of the tent of the assembly; and you will give them to the Levites, each {according to his required service}."
6 So Moses took the utility carts and the cattle, and he gave them to the Levites. 7 Two utility carts and four cattle he gave to the descendants of Gershon {according to their required service}; 8 and four utility carts and eight cattle he gave to the descendants of Merari {according to their required service}, {under the authority of} Ithamar son of Aaron the priest. 9 But to the descendants of Kohath he did not give [anything] because the work of the sanctuary they carried upon them on their shoulders.
