Behemoth is a large animal mentioned in the book of Job in the Bible. It is described as a powerful, grass-eating animal with great size and strength in comparison to humans. The description of Behemoth in Job 40 gives us the idea that this animal was an unstoppable, fearless creature. It is impossible to identify what species the Behemoth is, but we do know that it is a plant-eater that lives near water and is very strong and muscular. Some commentators identify the Behemoth as a hippopotamus, a rhinoceros, or an elephant, but the description of its cedar-like tail in Job 40:17 hardly fits the stubby or rope-like tails of those animals. Another theory is that Job 40 describes a type of dinosaur such as a diplodocus or an apatosaurus. However, the Bible does not reveal how long ago this initial creation took place, and it is impossible to know for sure what animal Behemoth refers to.
