Job 16:9

9. He teareth His anger teareth me and warreth against me. If Job ascribe his treatment to God, (Job 16:9-14,) his language transcends all bounds of reason; but if, on the contrary, he speaks of the malice of evil spirits to whose power he has been for a time delivered, it is nothing more than what might be expected from their diabolical nature, which is best imaged in the wildness and cruelty of the brute creation. Raschi, Cocceius, Adam Clarke, Tayler Lewis, and others, think that Job speaks here of Satan with his mocking fiends.

Gnasheth… with his teeth Such expressions appear often in the classics.

Sharpeneth his eyes An expression still in use in the East. The eye is here compared to a sword, or, as others suppose, to the fierce, fascinating gaze of the lion as he is about to pounce upon his prey.
