Numbers 10:8-10

Expanded Bible

⁸ “Aaron’s sons, the priests, should blow the trumpets. This is a ·law [perpetual/eternal regulation] for you and your descendants ·from now on [throughout your generations]. ⁹ When you are fighting an enemy who attacks you in your own land, blow the trumpets loudly. The Lord your God will ·take notice of [remember] you and will save you from your enemies. ¹⁰ Also blow your trumpets at happy times and during your feasts and at New Moon festivals [29:6; 1 Sam. 20:5; 2 Kin. 4:23; Ezra 3:5; Ps. 81:3; Is. 1:13; Amos 8:5]. Blow them over your burnt offerings [Lev. 1:1–17] and ·fellowship [or peace; well-being] offerings [Lev. 3:1], because they will help you remember your God. I am the Lord your God.”
