Quick Answer: Leviathan is a giant sea serpent noted in theology and mythology. It is referenced in the Hebrew Bible, as a metaphor for a powerful enemy, notably Babylon. It is referred to in Psalms, the Book of Job, the Book of Isaiah, and the pseudepigraphical Book of Enoch. Leviathan is often an embodiment of chaos, threatening to eat the damned when their lives are over. In the end, it is annihilated. Christian theologians identified Leviathan with the demon of the deadly sin envy. According to Ophite Diagrams, Leviathan encapsulates the space of the material world. In Gnosis, it encompasses the world like a sphere and incorporates the souls of those who are too attached to material things, so they cannot reach the realm of God's fullness beyond, from which all good emanates. In Hobbes, Leviathan becomes a metaphor for the omnipotence of the state, which maintains itself by educating children in its favour, generation after generation.
