American Standard Version

10 And Jehovah spake unto Moses, saying, ² Make thee two trumpets of silver; of ^[a]beaten work shalt thou make them: and thou shalt use them for the calling of the congregation, and for the journeying of the camps. ³ And when they shall blow them, all the congregation shall gather themselves unto thee at the door of the tent of meeting.
