Joshua 6:6-8

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

7He said to the people, “Go forward! March around the city, and let the armed men go 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 made of rams’ horns went on before the Lord and blew the trumpets; then the ark of the covenant of the Lord went behind them.
