Joshua 6:8-14

And it was so, that, when Joshua had spoken unto the people, the seven priests bearing the seven trumpets of rams’ horns before Jehovah passed on, and blew the trumpets: and the ark of the covenant of Jehovah followed them. And the armed men went before the priests that blew the trumpets, and the rearward went after the ark, the priests blowing the trumpets as they went. And 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. So he caused the ark of Jehovah to compass the city, going about it once: and they came into the camp, and lodged in the camp. And Joshua rose early in the morning, and the priests took up the ark of Jehovah. And the seven priests bearing the seven trumpets of rams’ horns before the ark of Jehovah went on continually, and blew the trumpets: and the armed men went before them; and the rearward came after the ark of Jehovah, the priests blowing the trumpets as they went. And the second day they compassed the city once, and returned into the camp: so they did six days.
