CLV(i)
1 Yahweh spoke to Moses, saying.
2 Make for yourself two bugles of silver. Out of a stiff shell shall you make them. And they will become yours for the calling of the congregation and for the journeying of the camps.
3 When they blow long on both of them, then the whole congregation will congregate with you at the opening of the tent of appointment.
4 Yet should they blow long on just one, then the princes, heads of the thousands of Israel, will congregate with you.
5 When you blow a short blast then the camps encamping eastward will journey.
