Numbers 10:1-6

¹And the Lord spoke to Moses, saying,

²Make to thyself two silver trumpets: thou shalt make them of beaten work; and they shall be to thee for the purpose of calling the assembly, and of removing the camps.

³And thou shalt sound with them, and all the congregation shall be gathered to the door of the tabernacle of witness.

⁴And if they shall sound with one, all the rulers even the princes of Israel shall come to thee.

⁵And ye shall sound an alarm, and the camps pitched eastward shall begin to move.

⁶And ye shall sound a second alarm, and the camps pitched southward shall move; and ye shall sound a third alarm, and the camps pitched westward shall move forward; and ye shall sound a fourth alarm, and they that encamp toward the north shall move forward: they shall sound an alarm at their departure.
