Numbers 10:7-9

Jubilee Bible 2000

⁷ But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm.

⁸ And the sons of Aaron, the priests, shall blow the trumpets; and you shall have them as a perpetual statute throughout your generations.

⁹ And when ye go to war in your land against the enemy that oppresses you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the LORD your God, and ye shall be saved from your enemies.
