[1] The LORD said to Moses: [2] “Make two trumpets of hammered silver, and use them for calling the community together and for having the camps set out. [3] When both are sounded, the whole community is to assemble before you at the entrance to the tent of meeting. [4] If only one is sounded, the leaders—the heads of the clans of Israel—are to assemble before you. [5] When a trumpet blast is sounded, the tribes camping on the east are to set out. [6] At the sounding of a second blast, the camps on the south are to set out. The blast will be the signal for setting out. [7] To gather the assembly, blow the trumpets, but not with the signal for setting out. [8] “The sons of Aaron, the priests, are to blow the trumpets. This is to be a lasting ordinance for you and the generations to come. [9] When you go into battle in your own land against an enemy who is oppressing you, sound a blast on the trumpets. Then you will be remembered by the LORD your God and rescued from your enemies. [10] Also at your times of rejoicing—your appointed festivals and New Moon feasts—you are to sound the trumpets over your burnt offerings and fellowship offerings, and they will be a memorial for you before your God. I am the LORD your God.”
