3And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation. 4And if they blow but with one trumpet, then the princes, which are heads of the thousands of Israel, shall gather themselves unto thee. 5When ye blow an alarm, then the camps that lie on the east parts shall go forward. 6When ye blow an alarm the second time, then the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys. 7But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm.
