Yehoshua 6:9-11

Orthodox Jewish Bible

⁹ And the armed men marched ahead of the Kohanim that blew with the shoferot, and the rear guard came after the Aron, with the shoferot of the Kohanim going on sounding.

¹⁰ Yehoshua had commanded HaAm, saying, Ye shall not shout, nor make any noise with your voice, neither shall any davar proceed out of your mouth, until the Yom I tell you to shout; then shall ye shout.

¹¹ So the Aron Hashem circled the Ir, going about it once; and they returned to the machaneh, and spent the night in the machaneh.
