When Moses called on the people to make their offerings for the erection of the sanctuary, it sorely vexed the princes of the tribes that he had not summoned them particularly. Hence they withheld their contributions, waiting for the people to give according to their powers, so that they might step in and make up the deficiency, and all should observe that without them the Tabernacle could not have been completed. But they were mistaken, for in their ready devotion the people provided all needful things for the sanctuary, and when the princes of the tribes perceived their mistake and brought their contributions, it was too late. All that they could do was to provide the jewels for the robes of the high priest, but they could no longer take a hand in the erection of the Tabernacle. On the day of the dedication they tried to make partial amends for letting slip their opportunity, by following the advice of the tribe of Issachar, renowned for wisdom and erudition, to bring wagons for the transportation of the Tabernacle. These princes of the tribes were no upstarts or men newly risen to honor, they were men who even in Egypt had been in office and exposed to the anger of the Egyptians; they had also stood at Moses' side when he undertook the census of the people. They now brought as an offering to Moses six covered wagons, fully equipped, and even painted blue, the color of the sky, and also twelve oxen to draw the wagons. The number of wagons as well as of oxen had been set with purpose. The six wagons corresponded to the six days of creation; to the six Mothers, Sarah, Rebekah, Rachel, Leah, Billhah, and Zilpah; to the six laws that the Torah prescribes exclusively for the king; to the six orders of the Mishnah, and to the six heavens. The number of the oxen corresponded to the twelve constellations, and to the twelve tribes. Moses did not at first want to accept the teams, but God not only bade him accept them, He also ordered him to address the princes kindly, and to thank them for their gifts. Moses now even thought the Shekinah had deserted him and would rest on the princes of the tribes, assuming that they had received direct communication from God to make this offering to the sanctuary. But God said to Moses: "If it had been a direct command from Me, then I should have ordered thee to tell them, but they did this on their own initiative, which indeed meets with My wish." Moses now accepted the gifts, not without misgivings, fearing lest a wagon should break, or an ox die, leaving the tribe or that unrepresented by a gift. But God assured him that no accident should occur to either wagon or ox, — yes, a great miracle came to pass in regard to these wagons and oxen, for the animals live forever without ailing or growing old, and the wagons likewise endure to all eternity.
