Bamidbar 10:5-7

Orthodox Jewish Bible

⁵ When ye sound a teruah, then the machanot that camp on the east shall go forward.

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.
