Numbers 7:3-8

3Together they brought six large wagons and twelve oxen. There was a wagon for every two leaders and an ox for each leader. They presented these to the Lord in front of the Tabernacle.

4Then the Lord said to Moses,

5“Receive their gifts, and use these oxen and wagons for transporting the Tabernacle. Distribute them among the Levites according to the work they have to do.”

6So Moses took the wagons and oxen and presented them to the Levites.

7He gave two wagons and four oxen to the Gershonite division for their work,

8and he gave four wagons and eight oxen to the Merarite division for their work. All their work was done under the leadership of Ithamar son of Aaron the priest.
