castles: The word tiroth, rendered "castles," is supposed by some to denote here "towers," fortified rocks, or mountain-tops, and fastnesses of various kinds in woods and hilly countries; but it rather means, "shepherds' cots," surrounded by sufficient enclosures to prevent the cattle from straying, as the cognate Syriac word teyaro, and Arabic tawar, signify "a sheep-fold."
