Behemoth

Behemoth (Hebrew behemot; Arabic bahīmūth, or bahamūt) is a creature mentioned in the Book of Job, 40:15-24.The word is most likely a plural form of bəhēmāh, meaning beast or large animal. It may be an example of pluralis excellentiae, a Hebrew method of expressing greatness by pluralizing a noun; it thus indicates that Behemoth is the largest and most powerful animal. Metaphorically, the name has come to be used for any extremely large or powerful entity.
The passage from the Book of Job describes Behemoth in this way: it was created along with man (40:15a), it is herbivorous (40:15b), it has strong muscles and bones, and it lives in the swamp (40:21).
Some have interpreted Behemoth as a mythical animal. However, some have attempted to identify it with real animals. In the book of Job, Behemoth is mentioned along with some mundane animals, such as goats, eagles, and hawks, making many Christian scholars to conclude that Behemoth may also be a mundane creature. Suggested animals include the water buffalo, rhinoceros and the elephant, but the most common suggestion is the hippopotamus. Many Young Earth Creationists propose that the Behemoth is a dinosaur.
