Joshua 6:8-14

And it was so, that when Joshua had spoken to the people, the seven priests carrying the seven trumpets of rams’ horns before the LORD went forward and blew the trumpets; and the ark of the covenant of the LORD followed them. The armed men went before the priests who blew the trumpets, and the rear guard came after the ark, while they continued to blow the trumpets. But Joshua commanded the people, saying, “You shall not shout nor let your voice be heard nor let a word proceed out of your mouth, until the day I tell you, ‘Shout!’ Then you shall shout!” So he had the ark of the LORD taken around the city, circling it once; then they came into the camp and spent the night in the camp. Now Joshua rose early in the morning, and the priests took up the ark of the LORD. The seven priests carrying the seven trumpets of rams’ horns before the ark of the LORD went on continually, and blew the trumpets; and the armed men went before them and the rear guard came after the ark of the LORD, while they continued to blow the trumpets. Thus the second day they marched around the city once and returned to the camp; they did so for six days.
