Job 41:22-25

22In his neck remaineth strength, and sorrow is turned into joy before him.1 23The flakes of his flesh are joined together: they are firm in themselves; they cannot be moved.2 24His heart is as firm as a stone; yea, as hard as a piece of the lower millstone . 25When he raiseth himself, the mighty are afraid: by reason of the crashing they purify themselves.
