Numbers
Chapters 10:1-4
Revised Version 1885
1And the Lord spake unto Moses, saying,
2Make thee two trumpets of silver; of beaten work shalt thou make them: and thou shalt use them for the calling of the congregation, and for the journeying of the camps.
3And when they shall blow with them, all the congregation shall gather themselves unto thee at the door of the tent of meeting.
4And if they blow but with one, then the princes, the heads of the thousands of Israel, shall gather themselves unto thee.
