Leviathan Leviathan Leviathan (; ) is a creature with the form of a sea monster from Jewish belief, referenced in the Hebrew Bible in the Book of Job, Psalms, the Book of Isaiah, and the Book of Amos. The Leviathan of the Book of Job is a reflection of the older Canaanite "Lotan", a primeval monster defeated by the god Hadad. Parallels to the role of Mesopotamian Tiamat defeated by Marduk have long been drawn in comparative mythology, as have been wider comparisons to dragon and world serpent narratives such as Indra slaying Vrtra or Thor slaying Jörmungandr, but Leviathan already
Leviathan as a sumptuous banquet for all the righteous in Heaven. According to Abraham Isaac Kook, the Leviathan – a singular creature with no mate, "its tail is placed in its mouth" (Zohar) "twisting around and encompassing the entire world" (Rashi on Baba Batra 74b) – projects a vivid metaphor for the universe’s underlying unity. This unity will only be revealed in the future, when the righteous will feast on the Leviathan. Leviathan can also be used as an image of Satan, endangering both God's creatures—by attempting to eat them—and God's creation—by threatening it with upheaval in the waters of Chaos.
