4 However, if one is sounded, only the leaders, the heads of Israel’s clans,k are to gather before you.

5 “When you sound short blasts, the camps pitched on the eastl are to set out. 6 When you sound short blasts a second time, the camps pitched on the southm 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.

9 “When you enter into battle in your land against an adversary who is attacking you, sound short blasts on the trumpets, and you will be remembered before the Lord your God and be saved from your enemies.n
