What kind of inner strength? (Job 23)

What kind of inner strength must it have taken for Job to stand up against the withering attacks from those around him, and to maintain his confidence toward God.

“I have stayed on God’s paths; … I have not departed from his commands, but have treasured his words more than my daily food.”

What commands was Job referring to? And which of God’s words did he so treasure? Perhaps he was referring to the ancient book of Enoch, the seventh from Adam. Perhaps in the past God had spoken audibly to Job.

Job complains of an impenetrable darkness, but there was light enough for him to see the faint outline of the Almighty at work – his purifying work. “And when he tests me, I will come out as pure as gold.”
