dol'-fool ('oach, "howling"): The "doleful creatures" referred to in Isaiah 13:21 are probably "jackals," although some have suggested "leopard," or "hyena." The older English Versions of the Bible gives "great owls." The word rendered "doleful lamentation" in Micah 2:4 (niheyah) is simply a form of the word ordinarily translated "wailing" (nehi). Compare the King James Version margin.
