Joshua 6:1-3

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.
