Numbers 7:7
Two wagons: Num 3:25, Num 3:26, Num 4:24-28 sons of Gershon: The Gershonites being fewest in number of able men, had the less burdensome things to carry; for they carried only the curtains, coverings, and hangings - Num 4:25, Num 4:40. And although this was a cumbersome carriage, and they needed waggons, yet it was not a heavy one, and they needed few.
