Numbers 10:6-8 Catholic Public Domain Version (CPDV)

6. Then, at the second sounding of the trumpet with the same cadence, those who live toward the south shall take up their tents. And the remainder shall act in like manner, when the trumpets shall reverberate for a departure.

7. But when the people are to be gathered together, the sound of the trumpets shall be simple, and the sounds shall not be separated.

8. Now it is the sons of Aaron the priest who shall sound the trumpets. And this shall be an everlasting ordinance, in your generations.
