Mark 9:18 in the King James Version
And wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out; and they could not.
Context
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 throws him down; and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, and they weren’t able.”
19 He answered him, “Unbelieving generation, how long shall I be with you? How long shall I bear with you? Bring him to me.”
