Job 41:24
King James Version
“His heart is as firm as a stone; yea, as hard as a piece of the nether”
Context
21His breath kindleth coals, and a flame goeth out of his mouth.
22In his neck remaineth strength, and sorrow is turned into joy before him.
23The flakes of his flesh are joined together: they are firm in themselves; they cannot be moved.
24His heart is as firm as a stone; yea, as hard as a piece of the nether
25When he raiseth up himself, the mighty are afraid: by reason of breakings they purify themselves.
26The sword of him that layeth at him cannot hold: the spear, the dart, nor the habergeon.
27He esteemeth iron as straw, brass as rotten wood.
