Mark 9:18 describes a boy suffering from violent seizures, with symptoms like foaming at the mouth, grinding his teeth, and becoming physically weak. The boy’s father tells Jesus that he asked the disciples to drive out the spirit causing this, but they were unable to do so. In this scene, the father is speaking directly to Jesus, explaining his son’s desperate condition and the failure of the disciples to help.

Question 2

The Greek behind Mark 9:18

Accepted Answer

The word “teareth” comes from ῥήσσει (rhēssei), which often means to break or shatter. Here, it paints a vivid picture of the spirit violently convulsing the boy, not just mild shaking. “Pineth away” is from ξηραίνω (xērainō), which means to wither or waste away. This suggests the boy’s strength and vitality are being drained over time, not just during the fits. “Could not” is from οὐκ ἴσχυσαν (ouk ischysan), meaning the disciples were not strong enough or did not have the power. This emphasizes a real limitation, not just a failed attempt.
