Numbers 10:8

“And the sons of Aaron the priests shall blow with the trumpets, etc.] Eleazar and Ithamar, the one with the one and the other with the other, there being at first but two, as there were but two priests; but in Solomon’s time there were an hundred twenty priests, and as many trumpets, (<140512>2 Chronicles 5:12); hence Maimonides says f102, there were never fewer than two trumpets, nor more than an hundred twenty; and they shall be to you for an ordinance for ever throughout your generations: for they were not only for present use, for the journeying of the camps in the wilderness, but for calling together the assembly in later times, as well as for other uses next mentioned; which would…”

“the sons of Aaron the priests shall blow with the trumpets, &c.--Neither the Levites nor any in the common ranks of the people could be employed in this office of signal giving.

“These trumpets were to be used for the holy purposes of the congregation generally, and therefore not only the making, but the manner of using them was prescribed by God Himself. They were to be blown by the priests alone, and "to be for an eternal ordinance to the families of Israel," i.e., to be preserved and used by them in all future times, according to the appointment of God. The blast of these trumpets was to call Israel to remembrance before Jehovah in time of war and on their feast-days. Num 10:9 "If ye go to war in your land against the enemy who oppresses you, and ye blow the trumpets, ye shall bring yourselves to remembrance before Jehovah, and shall be saved (by Him) from your…”
