what is a leviathan in the bible

The Leviathan is a sea serpent noted in theology and mythology, and is referenced 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 Leviathan is often depicted as a fearsome beast having monstrous ferocity and great power. However, biblical depictions of the Leviathan generally fall into one of two strains: terrifying monster linked to the Devil, or magnificent creation of God, evidence of his greatness and power. In Job 41, God describes Leviathan, emphasizing the animals size, strength, and viciousness. The Leviathan cannot be tied down or tamed, it is frightening to even look at, and it is best left alone. In Psalm 104, the Leviathan is described as a wondrous creation of God, and in Isaiah 27:1, it is a serpent and a symbol of Israel's enemies, who will be slain by God.
