Joshua 6:9 KJV

7And he said unto the people, Pass on, and compass the city, and let him that is armed pass on before the ark of the LORD.

8And it came to pass, when Joshua had spoken unto the people, that the seven priests bearing the seven trumpets of rams’ horns passed on before the LORD, and blew with the trumpets: and the ark of the covenant of the LORD followed them.

9And the armed men went before the priests that blew with the trumpets, and the rereward came after the ark, the priests going on, and blowing with the trumpets.

10And Joshua had commanded the people, saying, Ye shall not shout, nor make any noise with your voice, neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout.

11So the ark of the LORD compassed the city, going about it once: and they came into the camp, and lodged in the camp.
