Joshua 6:2-5

2The Lord said to Joshua, “I am about to hand Jericho, its king, and its warriors over to you.

3All the soldiers will march around the city once a day for six days.

4Seven priests will carry rams’ horns ahead of the ark. But on the seventh day you must march around the city seven times while the priests blow their horns.

5When you hear a long blast on the horn, all the troops must shout very loudly. The wall around the city will collapse. Then the troops must charge straight ahead into the city.”
