Joshua 6:6-10

6So Joshua son of Nun called the priests and said to them, “Take up the ark of the covenant of the LORD and have seven priests carry trumpets in front of it.”

7And he ordered the army, “Advance! March around the city, with an armed guard going ahead of the ark of the LORD .” 8When Joshua had spoken to the people, the seven priests carrying the seven trumpets before the LORD went forward, blowing their trumpets, and the ark of the LORD ’s covenant followed them. 9The armed guard marched ahead of the priests who blew the trumpets, and the rear guard followed the ark. All this time the trumpets were sounding. 10But 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!”
