Numbers 10:1-10 - The Silver Trumpets
2 Make thee two trumpets of silver, of beaten work, shalt thou make them, - and they shall be unto thee for calling the assembly, and for setting forward the camps. 3 As soon as they blow therewith, so soon hall all the assembly assemble themselves unto thee, unto the entrance of the tent of meeting. 4 And, if, only once, they blow, then shall the princes, the heads of the thousands of Israel, gather themselves unto thee.
5 But when ye blow an alarm, then shall set forward the camps that are encamped eastwards; 6 and when ye blow a second alarm, then shall set forward the camps that are encamped southwards, - an alarm, shall they blow for setting them forward, 7 But in calling together the convocation, ye shall blow but shall not sound an alarm. 8 And, the sons of Aaron the priests, shall blow with the trumpets, - and it shall be unto you for a statute age-abiding, unto your generations.
9 And when ye go into war in your land against thee assailant that assaileth you, then shall ye blow an alarm with the trumpets, - and bring yourselves to mind before Yahweh your God, and be saved, from your enemies, 10 And in your day of rejoicing and in your appointed seasons and in the beginnings of your months, then shall ye blow with the trumpets, over your ascending-sacrifices, and over your peace-offerings, - so shall they be unto you for a memorial before your God. I - Yahweh, am your God.
