Shout Down Your Walls - Joshua 5-6.

Joshua 6:3, 5, 10, 16, 20, 27 March around the city once with all the armed men. Do this for six days. When you hear them sound a long blast on the trumpets, have the whole army give a loud shout; then the wall of the city will collapse and the army will go up, everyone straight in.” But Joshua had commanded the army, “Do not give a war cry, do not raise your voices, do not say a word until the day I tell you to shout. Then shout!” The seventh time around, when the priests sounded the trumpet blast, Joshua commanded the army, “Shout! For the Lord has given you the city! When the trumpets sounded, the army shouted, and at the sound of the trumpet, when the men gave a loud shout, the wall collapsed; so everyone charged straight in, and they took the city. So the Lord was with Joshua, and his fame spread throughout the land.
