Joshua 6:11-14

He sent the Chest of GOD on its way around the city. It circled once, came back to camp, and stayed for the night. Joshua was up early the next morning and the priests took up the Chest of GOD. The seven priests carrying the seven ram’s horn trumpets marched before the Chest of GOD, marching and blowing the trumpets, with the armed guard marching before and the rear guard marching after. Marching and blowing of trumpets! On the second day they again circled the city once and returned to camp. They did this six days.
