Joshua 6:10-11

¹⁰ Now Joshua had commanded the people, saying, “You shall not shout or make any noise with your voice, nor shall a word proceed out of your mouth, until the day I say to you, ‘Shout!’ Then you shall shout.” ¹¹ So he had the ark of the Lord circle the city, going around it once. Then they came into the camp and ^[a]lodged in the camp.

Joshua 6:20

²⁰ 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.
