Job 40:15-19

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.
