Passage
and wherever it seizes him, it throws 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.”
and wherever it seizes him, it throws 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 9:16 He asked the scribes, “What are you asking them?”
Mark 9:17 One of the multitude answered, “Teacher, I brought to you my son, who has a mute spirit;
Mark 9:18 and wherever it seizes him, it throws 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 9:19 He answered him, “Unbelieving generation, how long shall I be with you? How long shall I bear with you? Bring him to me.”
Mark 9:20 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.
The verse centers on "wherever", "seizes", "throws", "down", "foams", "mouth", "grinds", and "teeth". It is saying that the verse draws attention to "wherever" and "seizes", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "One of the multitude answered Teacher I..." into verse 19's "He answered him Unbelieving generation how long...", so "wherever" and "seizes" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "wherever" and "seizes" with trust shaped by these words, not by a vague optimism outside the passage.
