Numbers 10:6 YLT

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.

⁷  'And in the assembling of the assembly ye blow, and do not shout;

⁸  and sons of Aaron, the priests, blow with the trumpets; and they have been to you for a statute age-during to your generations.
