Joshua 6:4, 5
Have seven priests carry seven rams’ horns in front of the ark. Then on the seventh day, march around the city seven times, while the priests blow the horns. / And when there is a long blast of the ram’s horn and you hear its sound, have all the people give a mighty shout. Then the wall of the city will collapse and all your people will charge straight into the city.”
