Numbers 10:1-6

The Silver Trumpets

1The  Lord spoke to Moses, saying, 2Make two silver trumpets. Of hammered work you shall make them, and you shall use them for a  summoning the congregation and for breaking camp. 3And when b  both are blown, all the congregation shall gather themselves to you at the entrance of the tent of meeting. 4But if they blow only one, then c  the chiefs, the heads of the tribes of Israel, shall gather themselves to you. 5When you blow an alarm, d  the camps that are on the east side shall set out. 6And when you blow an alarm the second time, e  the camps that are on the south side shall set out. An alarm is to be blown whenever they are to set out.
