Numbers 10:8-10

Contemporary English Version

⁸ The priests of Aaron's family will be the ones to blow the trumpets, and this law will never change.

⁹ Whenever you go into battle against an enemy attacking your land, give a warning signal on the trumpets. Then I, the Lord, will hear it and rescue you. ¹⁰ During the celebration of the New Moon Festival and other religious festivals, sound the trumpets while you offer sacrifices. This will be a reminder that I am the Lord your God.
