Numbers 10:2-4

Darby Translation

² Make thee two trumpets of silver; of beaten work shalt thou make them; and they shall serve for the calling together of the assembly, and for the journeying of the camps.

³ And when they shall blow with them, the whole assembly shall gather to thee at the entrance of the tent of meeting.

⁴ And if they blow with one, then the princes, the heads of the thousands of Israel, shall gather unto thee.
