John Gill's Bible Commentary Ver. 7. Two wagons and four oxen he gave unto the sons of Gershon , etc.] The eldest son of Levi: according to their service ; which was to bear and take care of the curtains, coverings, hangings and rails of the tabernacle; and which, when carrying from place to place, it was proper they should be covered from being exposed to rain and dust; and being so many as they were, must be heavy, burdensome, and cumbersome, and therefore two wagons, with two yoke of oxen, were given them, to ease them.
Matthew Henry Commentary
Verses 1-9 - The offering of the princes to the service of the tabernacle was no made till it was fully set up. Necessary observances must always tak place of free-will offerings. The more any are advanced, the greate opportunity they have of serving God and their generation. No soone was the tabernacle set up, than provision is made for the removal of it. Even when but just settled in the world, we must be preparing for changes and removes, especially for the great change.
