Moses then distributed the wagons among the Levites so that the division of the sons of Gershon received two wagons, with the transportation of the heavy portions of the Tabernacle, boards, bars, and similar things, whereas the former, having the lighter portions, had enough with two wagons. The third division of Levites, the sons of Kohath, received no wagons, for they were entrusted with the transportation of the Holy Ark, which might not be lifted upon a wagon, but was to be borne upon their shoulders. David, who forgot to observe this law and had the Ark lifted upon a wagon, paid heavily for his negligence, for the priests who tried to carry the Ark to the wagon were flung down upon the ground. Ahithophel then called David's attention to the need of following the example of Kohath's sons, who bore the Ark on their shoulders through the desert, and David ordered them to do the same. But the princes of the tribes were not content with having provided the means for transporting the sanctuary, they wanted to be the first, on the day of dedication, to present offerings. As with the wagons, Moses was doubtful whether or not to permit them to bring their offerings, for theses were of an unusual kind that were not ordinarily permissible. But God bade him accept the dedication offerings of the princes, though Moses was still in doubt whether to let all the twelve princes make their offerings on the same day, or to set a special day for each, and if so, in what order they should make their offerings. God thereupon revealed to him that each one of the princes of the tribes were to sacrifice on a special day, and that Nahshon, the prince of Judah, was to make the start. He was rewarded in this way for the devotion he had shown God during the passage through the Red Sea. When Israel, beset by the Egyptians, reached the sea, the tribes among themselves started quarreling who should first go into the sea. Then suddenly Nahshon, the prince of Judah, plunged into the sea, firmly trusting that God would stand by Israel in their need. [388]
