Numbers 10:5-7

EJ2000(i) 5 When ye blow an alarm, then ye shall move the camp of those that are lodged towards the east. 6 And when ye blow an alarm the second time, then ye shall move the camp of those that are lodged on the side of the Negev; they shall blow an alarm for their journeys. 7 But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm.
