Job 40:15-19

15Behold now behemoth, which I made with thee; he eateth grass as an ox.1 16Lo now, his strength is in his loins, and his force is in the sinew of his belly. 17He moveth his tail like a cedar: the sinews of his thighs are knit together.2 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 him .
