Numbers 10:7-9

Evangelical Heritage Version

⁷ When the community is to gather, you will blow the trumpets, but you will not sound the signal for setting out.

⁸ Aaron’s sons, the priests, will blow the trumpets. This will be a permanent regulation for you and for your descendants. ⁹ When you go out into battle in your own land against an adversary who attacks you, you will sound the signal with the trumpets. Then you will be remembered before the Lord your God, and you will be saved from your enemies.
