Numbers 10:1-5

KJV(i) 1 And the LORD spake unto Moses, saying, 2 Make thee two trumpets of silver; of a whole piece shalt thou make them: that thou mayest use them for the calling of the assembly, and for the journeying of the camps. 3 And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation. 4 And if they blow but with one trumpet, then the princes, which are heads of the thousands of Israel, shall gather themselves unto thee. 5 When ye blow an alarm, then the camps that lie on the east parts shall go forward.
