Job 33:19-25:

He [man] is chastened also with pain upon his bed, and the multitude of his bones with strong pain:
So that his life abhorreth bread, and his soul dainty meat.
His flesh is consumed away, that it cannot be seen; and his bones that were not seen stick out.
Yea, his soul draweth near unto the grave, and his life to the destroyers.
If there be a messenger with him, an interpreter, one among a thousand, to shew unto man his uprightness:
Then he is gracious unto him and saith, Deliver him from going down into the pit: I have found a ransom.
His flesh shall be fresher than a child’s: he shall return to the days of his youth:

Notes on Job 33:19-25:

These words came from Elihu, who was NOT one of the three “comforters” of whom God said that they did not speak what was right (Job 42:8).  God never corrected Elihu’s words, so we can safely accept them.  Some people believe that Elihu wrote the book of Job; arguments for and against that position are examined in the discussion Job Explained.
