Numbers 10:1-3

Young's Literal Translation

10 And Jehovah speaketh unto Moses, saying,

² `Make to thee two trumpets of silver; beaten work thou dost make them, and they have been to thee for the convocation of the company, and for the journeying of the camps;

³ and they have blown with them, and all the company have met together unto thee, unto the opening of the tent of meeting.
