Leviathan (Hebrew: לִוְיָתָן, Stanard Liwyatan Tiberian Liwyāṯān ; "Twisted; coiled") is a Biblical sea monster referred to in the Old Testament (Psalm 74:13-14; Job 41; Isaiah 27:1). The word leviathan has become synonymous with any large sea monster or creature. In the novel Moby-Dick it refers to great whales, and in Modern Hebrew, it means simply "whale".
