Joshua 6:6-8

6So Joshua son of Nun summoned the priests and said to them, “Take up the ark of the covenant and have seven priests carry seven rams’ horns in front of the ark of the Lord.”

7He said to the troops, “Move forward, march around the city, and have the armed men go ahead of the ark of the Lord.”

8After Joshua had spoken to the troops, seven priests carrying seven rams’ horns before the Lord moved forward and blew the rams’ horns; the ark of the Lord’s covenant followed them.
