 leviathan
      n 1: the largest or most massive thing of its kind; "it was a
           leviathan among redwoods"; "they were assigned the

 Leviathan
    a transliterated Hebrew word (livyathan), meaning "twisted,"
    "coiled." In Job 3:8, Revised Version, and marg. of Authorized
    Version, it denotes the dragon which, according to Eastern
    tradition, is an enemy of light; in 41:1 the crocodile is meant;
    in Ps. 104:26 it "denotes any large animal that moves by
    writhing or wriggling the body, the whale, the monsters of the
    deep." This word is also used figuratively for a cruel enemy, as
    some think "the Egyptian host, crushed by the divine power, and
    cast on the shores of the Red Sea" (Ps. 74:14). As used in Isa.
    27:1, "leviathan the piercing [R.V. 'swift'] serpent, even
    leviathan that crooked [R.V. marg. 'winding'] serpent," the word
    may probably denote the two empires, the Assyrian and the
    Babylonian.
