Behemoth (/bᵻˈhiːməθ/ or /ˈbiː.əməθ/, also /ˈbeɪ.əmɔːθ/; Hebrew: בהמות, behemoth (modern: behemot)) is a beast mentioned in Job 40:15–24. Suggested identities range from a mythological creature to an elephant, hippopotamus, rhinoceros, or buffalo. Some Young Earth creationistsbelieve it to be a description of a dinosaur. Metaphorically, the name has come to be used for any extremely large or powerful entity.
Job 40:15–24 describes Behemoth, and then the sea-monster Leviathan, to demonstrate to Job the futility of questioning God, who alone has created these beings and who alone can capture them. Both beasts are chaos monsters destroyed by the deity at the time of creation, although such a conflict is not found in the Genesis creation narrative.
Leviathan is identified figuratively with both the primeval sea (Job 3:8, Psalms 74:13) and in apocalyptic literature – describing the end-time – as that adversary, the Devil, from before creation who will finally be defeated. In the divine speeches in Job, Behemoth and Leviathan may both be seen as composite and mythical creatures with enormous strength, which humans like Job could not hope to control. But both are reduced to the status of divine pets, with rings through their noses and Leviathan on a leash.
