"15 Behold now behemoth, which I made with thee; he eateth grass as an ox. 16 Lo now, his strength is in his loins, and his force is in the navel of his belly. 17 He moveth his tail like a cedar: the sinews of his stones are wrapped together. 18 His bones are as strong pieces of brass; his bones are like bars of iron. 19 He is the chief of the ways of God: he that made him can make his sword to approach unto him. 20 Surely the mountains bring him forth food, where all the beasts of the field play. 23 Behold, he drinketh up a river, and hasteth not: he trusteth that he can draw up Jordan into his mouth. 24 He taketh it with his eyes: his nose pierceth through snares." Job 40:15-24 King James
The name "Behemoth" derives from the archaic Jewish name for hippopotamus, from the Hebrew behema. The Behemoth is a monster described in the Christian Bible, and is one of three primordial beasts said to symbolize the physical world; Behemoth represents the solid earth and is often depicted as a gigantic creature of unknown origin (though it has been identified with many large animals, such as hippos, elephants, or bulls).
Originally considered a chaos beast, the Behemoth was either confronted by God at the beginning of time or (somewhat confusingly) near the end of time; in both confrontations, the Behemoth is considered a hulking brute of unimaginable strength that is defeated by God's omnipotent nature and either banished or reduced to a divine "pet."
Behemoth is the beast of the earth, Leviathan is the beast of the sea, and Ziz is the beast of the air. Legend says that at the end of the world the Behemoth and Leviathan will kill each other, providing apocalyptic feasts for men.
