Numbers 10:9-10

Brenton(i) 9 And if ye shall go forth to war in your land against your enemies that are opposed to you, then shall ye sound with the trumpets; and ye shall be had in remembrance before the Lord, and ye shall be saved from your enemies. 10 And in the days of your gladness, and in your feasts, and in your new moons, ye shall sound with the trumpets at your whole-burnt-offerings, and at the sacrifices of your peace-offerings; and there shall be a memorial for you before your God: I am the Lord your God.
