Joshua 6:4-8

4Also seven priests shall carry seven 1trumpets of rams’ horns before the ark; then on the seventh day you shall march around the city seven times, and the priests shall blow the trumpets. 5It shall be that when they make a long blast with the ram’s horn, and when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city will fall down 2flat, and the people will go up every man 3straight ahead.”

6So Joshua the son of Nun called the priests and said to them, “Take up the ark of the covenant, and let seven priests carry seven trumpets of rams’ horns before the ark of the Lord.” 7Then 4he said to the people, “Go forward, and march around the city, and let the armed men go on before the ark of the Lord.” 8And 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.
