Joshua 6:4-13

4 with seven priests bearing seven trumpets of rams' horns before the ark. On the seventh day you shall march around the city seven times, the priests blowing the trumpets.
5 When they make a long blast with the ram's horn, as soon as you hear the sound of the trumpet, then all the people shall shout with a great shout; and the wall of the city will fall down flat, and all the people shall charge straight ahead."
6 So Joshua son of Nun summoned the priests and said to them, "Take up the ark of the covenant, and have seven priests carry seven trumpets of rams' horns in front of the ark of the Lord."
7 To the people he said, "Go forward and march around the city; have the armed men pass on before the ark of the Lord."
8 As Joshua had commanded the people, the seven priests carrying 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 And the armed men went before the priests who blew the trumpets; the rear guard came after the ark, while the trumpets blew continually.
10 To the people Joshua gave this command: "You shall not shout or let your voice be heard, nor shall you utter a word, until the day I tell you to shout. Then you shall shout."
11 So the ark of the Lord went around the city, circling 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 The seven priests carrying the seven trumpets of rams' horns before the ark of the Lord passed on, blowing the trumpets continually. The armed men went before them, and the rear guard came after the ark of the Lord, while the trumpets blew continually.
