Numbers 10:10

The Silver Signal-Trumpets. - Although God Himself appointed the time for removal and encampment by the movement of the cloud of His presence, signals were also requisite for ordering and conducting the march of so numerous a body, by means of which Moses, as commander-in-chief, might make known his commands to the different divisions of the camp. To this end God directed him to prepare two silver trumpets of beaten work (mikshah, see Exo 25:18), which should serve "for the calling of the assembly, and for the breaking up of the camps," i.e., which were to be used for this purpose. The form of these trumpets is not further described. No doubt they were straight, not curved, as we may infer both from the representation of these trumpets on the triumphal arch of Titus at Rome, and also from the fact, that none but straight trumpets occur on the old Egyptian monuments (see my Arch. ii. p. 187). With regard to the use of them for calling the congregation, the following directions are given in Num 10:3, Num 10:4 : "When they shall blow with them (i.e., with both), the whole congregation (in all its representatives) shall assemble at the door of the tabernacle; if they blow with only one, the princes or heads of the families of Israel shall assemble together."

In this chapter we have, I. Orders given about the making and using of silver trumpets, which seems to have been the last of all the commandments God gave upon mount Sinai, and one of the least, yet not without its significancy (Num 10:1-10). II. The history of the removal of Israel's camp from mount Sinai, and their orderly march into the wilderness of Paran (v. 11-28). III. Moses's treaty with Hobab, his brother-in-law (Num 10:29-32). IV. Moses's prayer at the removing and resting of the ark (Num 10:33, etc.).
