JOSHUA 6:9-11

⁹And the armed men went before the priests that blew the trumpets, and the rearward went after the ark, the priests blowing with the trumpets as they went.

¹⁰And Joshua commanded the people, saying, Ye shall not shout, nor let your voice be heard, neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout.

¹¹So he caused the ark of the LORD to compass the city, going about it once: and they came into the camp, and lodged in the camp.
