Job 40:17

15Behold now behemoth, which I made with thee; he eateth grass as an ox.

16Lo now, his strength is in his loins, and his force is in the navel of his belly.

17He moveth his tail like a cedar: the sinews of his stones are wrapped together.

18His bones are as strong pieces of brass; his bones are like bars of iron.

19He is the chief of the ways of God: he that made him can make his sword to approach unto him.
