Joshua 6:4-5 ▼

4 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 trumpets.

5 When there is a prolonged blast of the horn and you hear its sound, have all the people give a mighty shout. Then the city wall will collapse, and the people will advance, each man straight ahead.”
