And seven priests bearing seven trumpets of rams’ horns before the ark of the LORD went on continually, and blew with the trumpets: and the armed men went before them; but the rereward came after the ark of the LORD, the priests going on, and blowing with the trumpets.
Seven priests carried seven ram's horn trumpets in front of the LORD's ark and played them continuously. The armed soldiers went ahead, while those at the back followed the ark. The priests kept playing their trumpets as they moved.
