Numbers 7:3-8

3They brought these gifts to the Lord: six freight wagons and twelve oxen, one wagon from every two leaders and one ox from each leader. They brought them in front of the tent.

4The Lord said to Moses,

5“Accept these gifts from them to use in the work done for the tent of meeting. Give them to the Levites to use wherever they need these gifts for their work.”

6Moses took the wagons and the oxen and gave them to the Levites.

7He gave two wagons and four oxen to the Gershonites for the work they had to do.

8He gave four wagons and eight oxen to the Merarites for the work they had to do under the direction of Ithamar, son of the priest Aaron.
