Numbers 10:2

“Make thee two trumpets of silver, etc.] A metal very valuable and precious, durable, and fit for sound; only two are ordered, Aaron having but two sons, Eleazar and Ithamar, who were to blow with them, (<041008>Numbers 10:8); for though Moses’s order is, “make thee”, or for thee, yet not for his own use, but for the priests to use when he should order them: the Targum of Jonathan adds, of what is thine own, as if they were to be made at his own expense; but others say, and which is more probable, that they were to be made at the public expense: Josephus f100 gives a description of them, and says, that they were little less than a cubit long, the pipe of them narrow, but broader about the…”
