Joshua 6:1-5

Now Jericho [a fortified city with high walls] was tightly closed because [of the people’s fear] of the sons of Israel; no one went out or came in. The LORD said to Joshua, “See, I have given Jericho into your hand, with its king and the mighty warriors. Now you shall march around the city, all the men of war circling the city once. You shall do this [once each day] for six days. Also, seven priests shall carry seven trumpets [made] of rams’ horns ahead of the ark; then on the seventh day you shall march around the city seven times, and the priests shall blow the trumpets. When they make a long blast with the ram’s horn, and when you hear the sound of the trumpet, all the people shall cry out with a great shout (battle cry); and the wall of the city will fall down in its place, and the people shall go up, each man [going] straight ahead [climbing over the rubble].”
