Bamidbar 10:4-6

Orthodox Jewish Bible

⁴ And if they sound but with one, then the Nasi’im, which are heads of Yisroel’s thousands, shall gather themselves unto thee.

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.
