Adam Clarke on Matthew 12:22

One possessed with a devil, blind and dumb - A person from whom the indwelling demon took away both sight and hearing. Satan makes himself master of the heart, the eyes, and the tongue of the sinner. His heart he fills with the love of sin; his eyes he blinds that he may not see his guilt, and the perdition which awaits him; and his tongue he hinders from prayer and supplication, though he gives it increasing liberty in blasphemies, lies, slanders, etc. None but Jesus can redeem from this threefold captivity.
