Mark 9:18

18 and wherever it seizes him, it dashes him down, and he foams at the mouth, and grinds his teeth, and wastes away. I asked your disciples to cast it out, and they weren't able."

Mark 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).

Mark 9:18 In-Context

16 He asked the scribes, "What are you asking them?"

17 One of the multitude answered, "Teacher, I brought to you my son, who has a mute spirit;

18 and wherever it seizes him, it dashes him down, and he foams at the mouth, and grinds his teeth, and wastes away. I asked your disciples to cast it out, and they weren't able."

19 He answered him, "Unbelieving generation, how long will I be with you? How long will I bear with you? Bring him to me."

20 They brought him to him, and when he saw him, immediately the spirit convulsed him, and he fell on the ground, wallowing and foaming at the mouth.
