Joshua 6:4-6

International Standard Version

⁴ with seven priests carrying in front of the ark seven trumpets made from rams’ horns. On the seventh day march around the city seven times while the priests blow their trumpets. ⁵ When they sound a long blast with the ram’s horn, as soon as you hear the sound of the trumpet, then the entire army is to cry out loud, the city wall will collapse, and then all of the soldiers are to charge straight ahead.”

The Destruction of Jericho

⁶ So Nun’s son Joshua called for the priests. “Pick up the Ark of the Covenant,” he told them, “and have seven priests carry seven trumpets made from rams’ horns in front of the ark of the Lord.”
