Leviathan is a sea serpent or sea monster mentioned in several books of the Hebrew Bible, including Psalms, the Book of Job, the Book of Isaiah, the Book of Amos, and, according to some translations, in the Book of Jonah. The Hebrew word for Leviathan has the root meaning of "twisted" or "coiled". In the Old Testament, Leviathan appears as a multi-headed sea serpent that is killed by God and given as food to the Hebrews in the wilderness. In Isaiah 27:1, Leviathan is a serpent and a symbol of Israels enemies, who will be slain by God. In Job 41, it is a sea monster and a symbol of Gods power of creation. The Book of Enoch describes Leviathan as a female monster dwelling in the watery abyss, while Behemoth is a male monster living in the desert of Dunaydin. Christian theologians identified Leviathan with the demon of the deadly sin envy. According to some interpretations, Leviathan is a large aquatic creature, possibly a crocodile or a dragon, while others suggest it was a large reptile in the sea, perhaps one of the species of dinosaurs that roamed the earth before they went extinct.
