In the Bible, there are many references to items that may be different from what we know today. Have you ever wondered what David's slingshot looked like? It was not shaped like the letter Y with a rubberized band to hold the stone. It was than likely was a piece of woven hemp or leather with 2 strings attached to each side. It was then swung around and around and then released.
How about the trumpets and horns that sounded? Did they look like modern day band instruments? No.
