Numbers 10:8-10

Lexham English Bible

⁸ The sons of Aaron, the priests, will blow on the trumpets; this will be an eternal decree for your generations. ⁹ If you go to war in your land against the enemy who attacks you, you will signal with a loud noise on the trumpets. You will be remembered before^[a] Yahweh your God, and you will be rescued from your enemies.

¹⁰ “And on the day of your joy and in your appointed times, at the beginning of your months, you will blow on the trumpets in addition to your burnt offerings and in addition to the sacrifices of your fellowship offerings. And they will be as a memorial for you before^[b] your God; I am Yahweh your God.”
