Markos 9:18

18 And whenever it seizes him, it throws him into convulsions and he foams at the mouth, and grinds his teeth, and becomes rigid. And I told your talmidim in order that they might cast it out, and they did not have the koach.

Markos 9:18 Meaning and Commentary

Mark 9:18

And wheresoever he taketh him
The spirit, or devil, whether it be near fire, or water, whatsoever danger, or dangerous place:

he teareth him;
or throws him into it, or dashes him against it; or inwardly racks, tortures, and convulses him:

and he foameth;
at the mouth, like one that is mad:

and gnasheth with his teeth;
through the excessive pain he is in:

and pineth away;
his flesh is withered, dried up, and consumed away. This was the sad deplorable case this child was in, who was his father's only child, and therefore his health and life were very desirable: now he further observes to Christ, saying,

and I spake to thy disciples that they should cast him out, and
they could not.
Christ being absent, he entreated the disciples, who had power against unclean spirits, to cast them out; that they would make use of it, and dispossess this dumb and evil spirit; and who did make trial to cast him out, but were not able to effect it; (See Gill on Matthew 17:16).

Markos 9:18 In-Context

16 And Rebbe, Melech HaMoshiach questioned them, About what are you arguing with them?

17 And one of the multitude answered Rebbe, Melech HaMoshiach: Rabbi, I brought beni (my son) to you, because he has a shed that makes him illem (mute).

18 And whenever it seizes him, it throws him into convulsions and he foams at the mouth, and grinds his teeth, and becomes rigid. And I told your talmidim in order that they might cast it out, and they did not have the koach.

19 In reply to them, Rebbe, Melech HaMoshiach says, O dor without emunah, how long will I be with you? How long will I put up with you? Bring the bocher to me!

20 They brought the bocher to him. And when the shed saw Rebbe, Melech HaMoshiach, it threw the bocher into convulsions, and, falling to the ground, the bocher began rolling around foaming at the mouth.
