Joshua 6:5 WEB

³  You shall compass the city, all the men of war, going about the city once. Thus shall you do six days.

⁴  Seven priests shall bear seven trumpets of rams' horns before the ark: and the seventh day you shall compass the city seven times, and the priests shall blow the trumpets.

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.
