5. When you blow an alarm, then the camps that lie on the east side shall go forward.
6. When you blow an alarm the second time, then the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys.
7. But when the congregation is to be gathered together, you shall blow, but you shall not sound an alarm.
8. And the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an ordinance forever throughout your generations.
