2 “Make two trumpets of hammered silver to summon the community and have the camps set out.
3 When both are sounded in long blasts, the entire community is to gather before you at the entrance to the tent of meeting.
4 However, if one is sounded, only the leaders, the heads of Israel’s clans, are to gather before you.
5 “When you sound short blasts, the camps pitched on the east are to set out.
6 When you sound short blasts a second time, the camps pitched on the south are to set out. Short blasts are to be sounded for them to set out.
7 When calling the assembly together, you are to sound long blasts, not short ones.
8 The sons of Aaron, the priests, are to sound the trumpets. Your use of these is a permanent statute throughout your generations.
