Numbers 8:24
twenty-five <06242> [from twenty.]
In ch. 4:3, the Levites are appointed to the service of the tabernacle at the age of 30 years; and in 1 Ch 23:24, they are ordered to commence their work at 20 years of age. In order to reconcile this apparent discrepancy, it is to be observed, 1. At the time of which Moses speaks in ch. 4:3, the Levitical service was exceedingly severe, and consequently required full grown, robust men, to perform it; the age of 30 was therefore appointed as the period for commencing this service, the weightier part of which was probably there intended. 2. In this place God seems to speak of the service in a general way: hence the age of 25 is fixed. 3. In David's time, and afterwards, in the fixed tabernacle and temple, the laboriousness of the service no longer existed, and hence 20 years was the age appointed.

Numbers 10:2
two trumpets <02689 08147> [two trumpets.]
The necessity of such instruments will at once appear, when the amazing extent of this army is considered. There were various kinds of trumpets among the ancients, of different forms and materials, as Eustathius shews on Homer, where he mentions six; the second of which was [stroggule,] turned up round, like a ram's horn; which he says the Egyptians used (from being invented by Osiris) when they assembled the people to their sacrifices. But in opposition to that form, Moses commands these to be made long, in the shape of those used at present. So Josephus informs us, who says they were near a cubit long; the tube of the thickness of a common pipe or flute; the mouth no wider than just to admit blowing into them; and their ends wide like those of a modern trumpet.
