Kill every one of them (as he said, Job 40:12) at one blow, as I can do, and bring them all to their graves, that they may sleep in the dust, and never offend thee nor trouble others more. Bind their faces, i.e. condemn or destroy them. He alludes to the manner of covering the faces of condemned persons, Esther 7:8, and of dead men, 1 Thessalonians 11:44, 1 Thessalonians 20:7. See Poole on "Job 9:21". In secret; either in a secret place, bury them in their graves; or secretly, with a secret and invisible stroke, that it may appear it comes from the hand of a God.
