Joshua 6:7 WEB

⁵  It shall be that when they make a long blast with the ram's horn, and when you hear the sound of the trumpet, all the people shall shout with a great shout; and the wall of the city shall fall down flat, and the people shall go up every man straight before him.

⁶  Joshua the son of Nun called the priests, and said to them, Take up the ark of the covenant, and let seven priests bear seven trumpets of rams' horns before the ark of Yahweh.

⁷  They said to the people, Pass on, and compass the city, and let the armed men pass on before the ark of Yahweh.

⁸  It was so, that when Joshua had spoken to the people, the seven priests bearing the seven trumpets of rams' horns before Yahweh passed on, and blew the trumpets: and the ark of the covenant of Yahweh followed them.

⁹  The armed men went before the priests who blew the trumpets, and the rearward went after the ark, [the priests] blowing the trumpets as they went.
