Numbers 7:7-9

New Century Version

⁷ He gave two carts and four oxen to the Gershonites, which they needed for their work. ⁸ Then Moses gave four carts and eight oxen to the Merarites, which they needed for their work. Ithamar son of Aaron, the priest, directed the work of all of them. ⁹ Moses did not give any oxen or carts to the Kohathites, because their job was to carry the holy things on their shoulders.
