Numbers 10:3-7

³And you shall 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 you.

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

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

⁷And whenever you° shall gather the assembly, you° shall sound, but not an alarm.
