Numbers 10:7 ASV

⁵  And when ye blow an alarm, the camps that lie on the east side shall take their journey.

⁶  And when ye blow an alarm the second time, the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys.

⁷  But when the assembly 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 they shall be to you for a statute for ever throughout your generations.

⁹  And when ye go to war in your land against the adversary that oppresseth you, then ye shall sound an alarm with the trumpets; and ye shall be remembered before Jehovah your God, and ye shall be saved from your enemies.
