Numbers 10

Num 10:1 The LORD said to Moses,
Num 10:2 "Make two trumpets of hammered silver to use for calling the people together and for breaking camp.
Num 10:3 When long blasts are sounded on both trumpets, the whole community is to gather around you at the entrance to the Tent of my presence.
Num 10:4 But when only one trumpet is sounded, then only the leaders of the clans are to gather around you.
Num 10:5 When short blasts are sounded, the tribes camped on the east will move out.
Num 10:6 When short blasts are sounded a second time, the tribes on the south will move out. So short blasts are to be sounded to break camp,
Num 10:7 but in order to call the community together, long blasts are to be sounded.
Num 10:8 The trumpets are to be blown by Aaron's sons, the priests. "The following rule is to be observed for all time to come.

I remember my boy scouts days. One part of the boy scouts training is deciphering whistle codes. There’s a whistle for general assembly, a whistle for troop leaders assembly, a whistle for emergency. It’s really all about learning order and discipline. This is the same for the early Israelites as it is for today.


Num 10:9 When you are at war in your land, defending yourselves against an enemy who has attacked you, sound the signal for battle on these trumpets. I, the LORD your God, will help you and save you from your enemies.

God’s assurance for his people never changed as it was during the early Israelites’ days and today.
