THE USE OF THE SILVER TRUMPETS. (Num. 10:1-36) Make thee two trumpets of silver--These trumpets were of a long form, in opposition to that of the Egyptian trumpets, with which the people were convened to the worship of Osiris and which were curved like rams' horns. Those which Moses made, as described by JOSEPHUS and represented on the arch of Titus, were straight, a cubit or more in length, the tubes of the thickness of a flute. Both extremities bore a close resemblance to those in use among us. They were of solid silver--so as, from the purity of the metal, to give a shrill, distinct sound; and there were two of them, probably because there were only two sons of Aaron; but at a later period the number was greatly increased (Jos 6:8; Ch2 5:12). And although the camp comprehended 2,500,000 of people, two trumpets would be quite sufficient, for sound is conveyed easily through the pure atmosphere and reverberated strongly among the valleys of the Sinaitic hills.
