Numbers 10:6 ASV

⁴  And if they blow but one, then the princes, the heads of the thousands of Israel, shall gather themselves unto thee.

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.
