Make 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.
Also in the day of your gladness, and in your set feasts, and in the beginnings of your months, ye shall blow the trumpets over your burnt-offerings, and over the sacrifices of your peace-offerings; and they shall be to you for a memorial before your God: I am Jehovah your God.
And in the seventh month, on the first day of the month, ye shall have a holy convocation; ye shall do no servile work: it is a day of blowing of trumpets unto you.
Then shalt thou send abroad the loud trumpet on the tenth day of the seventh month; in the day of atonement shall ye send abroad the trumpet throughout all your land.
