10 The Lord spoke to Moses, saying, 2 “Make two silver trumpets. Of hammered work you shall make them, and you shall use them for xsummoning the congregation and for breaking camp. 3 And when yboth are blown, all the congregation shall gather themselves to you at the entrance of the tent of meeting. 4 But if they blow only one, then zthe chiefs, the heads of the tribes of Israel, shall gather themselves to you. 5 When you blow an alarm, athe camps that are on the east side shall set out. 6 And when you blow an alarm the second time, bthe camps that are on the south side shall set out. An alarm is to be blown whenever they are to set out. 7 But when the assembly is to be gathered together, cyou shall blow a long blast, but you shall not dsound an alarm. 8 eAnd the sons of Aaron, the priests, shall blow the trumpets. The trumpets shall be to you for a perpetual statute throughout your generations. 9 And fwhen you go to war in your land against the adversary who goppresses you, then you shall dsound an alarm with the trumpets, that you may be hremembered before the Lord your God, and you shall be saved from your enemies.
