Ezra 4:2; Ezra 21:22. A mound was usually raised, on which the ram was planted, to be on a level with the walls. The ram was sometimes fixed, or else joined to moveable wooden towers containing warriors. It was hung by a rope, whereby the men inside swung it forward and backward. The besieged by a double rope from the battlements tried to catch the ram, or else threw lighted torches on it.
