Numbers 10:2-3
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.
