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 have seven priests carry seven trumpets of rams’ horns in front of the ark of the Lord.”

7Then 1he said to the people, “Go forward and march around the city, and the armed men shall go on ahead of 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.
