Numbers 10:2-10

2“Make two trumpets out of hammered silver. Use them to call the community together and as a signal to break camp.

3When you blow both trumpets, the whole community will meet with you at the entrance to the tent of meeting.

4If only one trumpet blows, the leaders, the heads of the divisions of Israel, will meet with you.

5When they hear the trumpet fanfare, the tribes that are camped on the east side will break camp first.

6When the trumpets sound a second fanfare, the tribes that are camped on the south will break camp. The fanfare is the signal to break camp.

7But when you gather the assembly, the trumpets will blow without sounding a fanfare.

8The sons of Aaron, the priests, will blow the trumpets. This will be a permanent law for you and your descendants.

9“When you go to war in your own country against an enemy who is oppressing you, the trumpets will sound a fanfare. Then the Lord your God will remember you and rescue you from your enemies.

10Also, on your festival days and on the first day of the month, blow the trumpets when you sacrifice your burnt offerings and fellowship offerings. The trumpets will be a reminder for you in God’s presence. I am the Lord your God.”
