Bamidbar 10:6-8

Orthodox Jewish Bible

⁶ When ye sound a teruah the second time, then the machanot that camp on the south shall set out; they shall sound a teruah for their settings out.

⁷ But when the Kahal is to be gathered together, ye shall sound it, but ye shall not sound a teruah.

⁸ And the Bnei Aharon, the kohanim, shall sound the tzotzerot; and they shall be to you for a chukkat olam throughout your dorot.
