Numbers 10:7-9

English Standard Version

⁷ But when the assembly is to be gathered together, ^(A)you shall blow a long blast, but you shall not ^(B)sound an alarm. ^8 (C)And the sons of Aaron, the priests, shall blow the trumpets. The trumpets shall be to you for a perpetual statute throughout your generations. ⁹ And ^(D)when you go to war in your land against the adversary who ^(E)oppresses you, then you shall ^(F)sound an alarm with the trumpets, that you may be ^(G)remembered before the Lord your God, and you shall be saved from your enemies.
