Joshua 6:3-5

3You shall march around the city, all the men of war circling the city once. You shall do so for six days. 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.”
