MSB(i)
1 Then the LORD said to Moses,
2 “Make two trumpets of hammered silver to be used for calling the congregation and for having the camps set out.
3 When both are sounded, the whole congregation is to assemble before you at the entrance to the Tent of Meeting.
4 But if only one is sounded, then the leaders, the heads of the clans of Israel, are to gather before you.
5 When you sound short blasts, the camps that lie on the east side are to set out.
