Numbers 10:4 YLT

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.

⁴  And if with one they blow, then have the princes, heads of the thousands of Israel, met together unto thee;

⁵  'And ye have blown -- a shout, and the camps which are encamping eastward have journeyed.

⁶  'And ye have blown -- a second shout, and the camps which are encamping southward have journeyed; a shout they blow for their journeys.
