And, lo, a spirit taketh him
 An evil spirit, the devil, as in ( Luke 9:42 ) seizes and possesses him at once, 
 and he suddenly crieth out;
 in a most terrible manner, giving dreadful shrieks, as soon as he perceives that he is seized by the demon: 
 and it teareth him, that he foameth again;
 throws him into convulsions, so that he foams at the mouth: and so we read F20 of a son of a certain Jew, that 
``a certain spirit passed before him and hurt him, convulsed his mouth, and his eyes, and his hands were convulsed, and he could not speak.''And bruising him;
 hardly departeth from him;
 is very loath to leave him, even after he has distressed, convulsed, and bruised him in this dreadful manner, such was his cruelty and malice; (See Gill on Matthew 17:15) (See Gill on Mark 9:18)
