The sons of Aaron - As the trumpets were emblematic of the voice of God, the priests only were to use them. At this time there were only two “sons of Aaron;” but in later times, when the number of priests was greater, more trumpets were used; we read of seven in the times of Joshua and David (see the marginal references.); and of a hundred and twenty in that of Solomon 2 Chronicles 5:12.
