Job 41:20-24

Out of his nostrils goeth smoke, as out of a seething pot or caldron.

His breath kindleth coals, and a flame goeth out of his mouth.

In his neck remaineth strength, and sorrow is turned into joy before him.

The flakes of his flesh are joined together: they are firm in themselves; they cannot be moved.

His heart is as firm as a stone; yea, as hard as a piece of the nether millstone.
