Job 40:16

14 Then I will confess to you that your own right hand can save you.

15 Look at Behemoth, which I made along with you. He feeds on grass like an ox.

See the strength of his loins and the power in the muscles of his belly.

17 His tail sways like a cedar; the sinews of his thighs are tightly knit.

18 His bones are tubes of bronze; his limbs are rods of iron.

Do read the surrounding verses too, because the context often says more than a single verse.
