Joshua 6:1-5

Now the gates of Jericho were bolted and barred because of the Israelites; no one could get in or out. YAHWEH commanded Joshua, “See, I have given Jericho, its king and mighty warriors into your hands. March around the city with all your men of war once a day for six days. Have seven priests carry shofars in front of the ark. On the seventh day, march around the city seven times, with the priests blowing the shofars. When you hear the blare of the shofars, have all the people shout with a mighty shout of joy! Then the walls of the city will collapse before your eyes, and your whole army must charge straight in!”
