'Alarm' in the Bible

When you sound an alarm, the ones encamped on the east side are to begin to travel.

When you sound the alarm the second time, those encamped on the south are to begin to travel. Alarms are to be sounded for their travels.

But when you blow the trumpet to assemble the whole congregation, don't use the same sound as you do for sounding an alarm.

"When you wage war in your land against an enemy who is hostile to you, you are to sound an alarm with the trumpets. Then you will be remembered before the face of the LORD your God and you will be delivered from your enemies.
