3 When both are sounded, the whole community is to assemble before you at the entrance to the tent of meeting.
4 If only one is sounded, the leaders—the heads of the clans of Israel—are to assemble before you.
5 When a trumpet blast is sounded, the tribes camping on the east are to set out.
6 At the sounding of a second blast, the camps on the south are to set out. The blast will be the signal for setting out.
7 To gather the assembly, blow the trumpets, but not with the signal for setting out.
8 “The sons of Aaron, the priests, are to blow the trumpets. This is to be a lasting ordinance for you and the generations to come.
9 When you go into battle in your own land against an enemy who is oppressing you, sound a blast on the trumpets. Then you will be remembered by the Lord your God and rescued from your enemies.
