4 but when one of them is blown, only the tribal leaders, the heads of the clans of Israel, shall gather round you.
5 When you sound the signal, those encamped on the east side shall break camp;
6 when you sound a second signal, those encamped on the south side shall break camp; when you sound a third signal, those encamped on the west side shall break camp; when you sound a fourth signal, those encamped on the north side shall break camp. Thus shall the signal be sounded for them to break camp.
7 But in calling forth an assembly you are to blow a blast, without sounding the signal.
8 The sons of Aaron, the priests, shall blow the trumpets; this is prescribed forever for you and your descendants.
9 When in your own land you go to war against an enemy that is attacking you, you shall sound the alarm on the trumpets, and you shall be remembered before the Lord, your God, and be saved from your foes.
10 And when you rejoice on your festivals, and your new-moon feasts, you shall blow the trumpets over your burnt offerings and your communion sacrifices, so that this serves as a reminder of you before your God. I, the Lord, am your God.
