Joshua 6:6-8

6So Joshua the son of Nun called the priests and said to them, “Take up the ark of the covenant, and let seven priests carry seven trumpets of rams’ horns before the ark of the Lord.”

7Then 1he said to the people, “Go forward, and march around the city, and let the armed men go on before the ark of the Lord.”

8And it was so, that when Joshua had spoken to the people, the seven priests carrying the seven trumpets of rams’ horns before the Lord went forward and blew the trumpets; and the ark of the covenant of the Lord followed them.
