Numbers 10:7 DBY

⁵  And when ye blow an alarm, the camps that lie eastward shall set forward.

⁶  And when ye blow an alarm the second time, the camps that lie southward shall set forward; they shall blow an alarm on their setting forward.

⁷  And when the congregation is to be gathered together, ye shall blow, but ye shall not blow an alarm:

⁸  the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an everlasting statute throughout your generations.

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