Orthodox Jewish Bible

³ And when they shall sound them, Kol HaEdah shall assemble themselves to thee at the entrance of the Ohel Mo’ed.

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.
