The largest and most powerful beast to ever exist, the king of all land animals.

He is the male counterpart to the female Leviathan, lord of the ocean.

At the End of Days, God will command the Behemoth and the Leviathan to battle to the death, then a feast of their flesh will be served to the righteous.

From the Holy Bible:

Behold now behemoth, which I made with thee; he eateth grass as an ox. Lo now, his strength is in his loins, and his force is in the navel of his belly. He moveth his tail like a cedar: the sinews of his stones are wrapped together. His bones are as strong pieces of brass; his bones are like bars of iron. He is the chief of the ways of God: he that made him can make his sword to approach unto him.

Surely the mountains bring him forth food, where all the beasts of the field play. He lieth under the shady trees, in the covert of the reed, and fens. The shady trees cover him with their shadow; the willows of the brook compass him about. Behold, he drinketh up a river, and hasteth not: he trusteth that he can draw up Jordan into his mouth. He taketh it with his eyes: his nose pierceth through snares (Job 40:14-24 King James Version).

The word behemoth may also be used to describe any exceptionally large or powerful entity.
