Jamieson-Fausset-Brown Bible Commentary

2, 3. the princes of Israel . brought their offering before the Lord-The finishing of the sacred edifice would, it may well be imagined, be hailed as an auspicious occasion, diffusing great joy and thankfulness throughout the whole population of Israel. But the leading men, not content with participating in the general expression of satisfaction, distinguished themselves by a movement, which, while purely spontaneous, was at the same time so appropriate in the circumstances and so equal in character, as indicates it to have been the result of concerted and previous arrangement. It was an offer of the means of carriage, suitable to the migratory state of the nation in the wilderness, for transporting the tabernacle from place to place. In the pattern of that sacred tent exhibited on the mount, and to which its symbolic and typical character required a faithful adherence, no provision had been made for its removal in the frequent journeyings of the Israelites. That not being essential to the plan of the divine architect, it was left to be accomplished by voluntary liberality; and whether we look to the judicious character of the gifts, or to the public manner in which they were presented, we have unmistakable evidence of the pious and patriotic feelings from which they emanated and the extensive interest the occasion produced. The offerers were "the princes of Israel, heads of the house of their fathers," and the offering consisted of six covered wagons or little cars, and twelve oxen, two of the princes being partners in a wagon, and each furnishing an ox.

Matthew Henry's Concise Commentary

7:1-9 The offering of the princes to the service of the tabernacle was not made till it was fully set up. Necessary observances must always take place of free-will offerings. The more any are advanced, the greater opportunity they have of serving God and their generation. No sooner 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.
