6 So Joshua the son of Nun called the priests and said to them, “Take up the ark of the covenant and let seven priests bear seven trumpets of rams' horns before the ark of the Lord.” 7 And he said to the people, “Go forward. March around the city and let the armed men pass on before the ark of the Lord.”
8 And just as Joshua had commanded the people, the seven priests bearing the seven trumpets of rams' horns before the Lord went forward, blowing the trumpets, with the ark of the covenant of the Lord following them. 9 The armed men were walking before the priests who were blowing the trumpets, and the rear guard was walking after the ark, while the trumpets blew continually. 10 But Joshua commanded the people, “You shall not shout or make your voice heard, neither shall any word go out of your mouth, until the day I tell you to shout. Then you shall shout.” 11 So he caused the ark of the Lord to circle the city, going about it once. And they came into the camp and spent the night in the camp.
12 Then Joshua rose early in the morning, and the priests took up the ark of the Lord. 13 And the seven priests bearing the seven trumpets of rams' horns before the ark of the Lord walked on, and they blew the trumpets continually. And the armed men were walking before them, and the rear guard was walking after the ark of the Lord, while the trumpets blew continually. 14 And the second day they marched around the city once, and returned into the camp. So they did for six days. (ESV)
