Context Reading
2“Make two trumpets of silver. You shall make them of beaten work. You shall use them for the calling of the congregation and for the journeying of the camps. 3When they blow them, all the congregation shall gather themselves to you at the door of the Tent of Meeting. 4If they blow just one, then the princes, the heads of the thousands of Israel, shall gather themselves to you. 5When you blow an alarm, the camps that lie on the east side shall go forward. 6When you blow an alarm the second time, the camps that lie on the south side shall go forward. They shall blow an alarm for their journeys.
