Mark 9:18
18 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.
Chapter Context
Mark 9 is a action-oriented gospel chapter in the New Testament that explores themes of worship, redemption, hope. Written during the mid first century CE (c. 65-70 CE), this chapter should be understood within its historical context: Composed during or just after Nero's persecution when eyewitnesses were disappearing.
The chapter can be divided into several sections:
- Verses 1-5: Introduction and setting the context
- Verses 6-12: Development of key themes
- Verses 13-20: Central message and teachings
- Verses 21-50: Conclusion and application
This chapter is significant because it foreshadows Christ's work through typology and prophetic elements. When studying this passage, it's important to consider both its immediate context within Mark and its broader place in the scriptural canon.

Mark 9:18
18 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.
Analysis
The father describes his son's condition: 'wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away' (ὅπου ἐὰν αὐτὸν καταλάβῃ, ῥήσσει αὐτόν, καὶ ἀφρίζει καὶ τρίζει τοὺς ὀδόντας). The violent symptoms—tearing (rhēssei, ῥήσσει), foaming (aphrizei, ἀφρίζει), gnashing teeth (trizei, τρίζει), and wasting away (xērainetai, ξηραίνεται)—describe severe demonic torment. The demon's goal is destruction (v. 22 states it tried to kill the boy). This illustrates Satan's character as thief who comes 'to steal, and to kill, and to destroy' (John 10:10). The father adds, 'I spake to thy disciples that they should cast him out; and they could not' (εἶπα τοῖς μαθηταῖς σου ἵνα αὐτὸ ἐκβάλωσιν, καὶ οὐκ ἴσχυσαν). The disciples' inability (ouk ischysan, οὐκ ἴσχυσαν, 'they had no strength') reveals spiritual powerlessness when faith and prayer are lacking (v. 29).
Historical Context
The symptoms described—seizures, foaming, rigidity—resemble epilepsy, leading some modern interpreters to naturalize the account. However, Mark clearly attributes the condition to demonic agency (vv. 17, 20, 25). Biblical worldview doesn't deny physical causes but recognizes spiritual warfare as reality. The disciples had successfully cast out demons earlier (Mark 6:13), making their failure here surprising. Jesus later explains that 'this kind can come forth by nothing, but by prayer and fasting' (v. 29), indicating different levels of demonic opposition requiring deeper spiritual discipline. The father's disappointment at the disciples' failure mirrors human disappointment when Christian ministry appears powerless.
Reflection
- How does the demon's destructive intent illustrate Satan's character and ultimate goal toward humanity?
- What does the disciples' inability despite previous success teach about the necessity of ongoing spiritual discipline and dependence on God?
