Joshua 6:3-5

March around the city with all the men of war, circling the city one time. Do this for six days. Have seven priests carry seven ram’s-horn trumpets in front of the ark. But on the seventh day, march around the city seven times, while the priests blow the rams’ horns. When there is a prolonged blast of the horn and you hear its sound, have all the troops give a mighty shout. Then the city wall will collapse, and the troops will advance, each man straight ahead.”
