^4-7 “When a bugle gives a single, short blast, that’s the signal for the leaders, the heads of the clans, to assemble. When it gives a long blast, that’s the signal to march. At the first blast the tribes who were camped on the east set out. At the second blast the camps on the south set out. The long blasts are the signals to march. The bugle call that gathers the assembly is different from the signal to march.

^8-10 “The sons of Aaron, the priests, are in charge of blowing the bugles; it’s their assigned duty down through the generations. When you go to war against an aggressor, blow a long blast on the bugle so that God will notice you and deliver you from your enemies. Also at times of celebration, at the appointed feasts and New Moon festivals, blow the bugles over your Whole-Burnt-Offerings and Peace-Offerings: they will keep your attention on God. I am God, your God.”
