Num Numbers, chapter Book of Numbers, chapter 10
And when ye blow an alarm, the camps that lie on the east side shall take their journey. Num 2:3And when ye blow an alarm the second time, the camps that lie on the south side shall set forward; they shall blow an alarm for their journeys. Num 2:10But when the assembly is to be gathered together, ye shall blow, but ye shall not sound an alarm.
