Joshua 6
6 Ref Then Joshua, the son of Nun, sent for the priests and said to them, Take up the ark of the agreement, and let seven priests take seven horns in their hands and go before the ark of the Lord.
7 Ref And he said to the people, Go forward, circling the town, and let the armed men go before the ark of the Lord.
8 Ref So after Joshua had said this to the people, the seven priests with their seven horns went forward before the Lord, blowing on their horns: and the ark of the Lord's agreement went after them.
