This verse in the King James

King James wording
And I besought thy disciples to cast him out; and they could not.

A real appeal and a real need do not create capacity in the people asked to help; the verse names their inability plainly.

An urgent need can reach the people expected to help and still exceed their ability. The verse gives that limit an honest name: they could not.

WHAT THIS UNDOES

It undoes the belief that if a need is real, the people asked must be able to meet it.

ἠδυνήθησαν

ēdynēthēsan

GROWS FROM

δύναμαι

dynamai

To be able; to have strength or capacity.

“could not” in this verse is ēdynēthēsan. The verb names an actual limit in ability: the disciples lack the capacity to do what is asked. Its family also names power and possibility, placing the need beside a clear limit in what they can do.

ALSO GROWS

dynamis: Power or capacity.

δύναμις

This branch makes the verse’s stated lack of ability a question of capacity.

dynatos: Able; possible.

δυνατός

This branch links what someone can do with what is possible, sharpening the contrast between the request and the disciples’ limit.

παρεκάλεσα

parekalesa

GROWS FROM

παρακαλέω

parakaleō

To appeal, urge, encourage, or comfort, depending on context.

“begged” in this verse is parekalesa. The father’s word is an appeal for help. This word family also carries the sense of encouragement and comfort, but here the appeal meets an inability.

ALSO GROWS

paraklēsis: An appeal, encouragement, or consolation.

παράκλησις

This branch shows the plea as an appeal for help, not a casual request.

paraklētos: An advocate or helper; in some contexts, a comforter.

παράκλητος

This branch echoes the need for help that the father brings to the disciples.

ἐκβαλεῖν

ekbalein

GROWS FROM

ἐκβάλλω

ekballō

To throw or drive something out.

“cast him out” in this verse is ekbalein. The request is for the harmful presence to be put out; it is a concrete demand for removal. The compound joins ⁨ἐκ⁩ (ek, out) with ⁨βάλλω⁩ (ballō, throw or cast), setting that demand beside the disciples’ stated lack of power.

ALSO GROWS

ballō: To throw or cast.

βάλλω

This is the action carried within the request to cast the affliction out.

ekbolē: A casting out or expulsion.

ἐκβολή

This related noun makes the outward direction of the requested removal explicit.

A real need can exceed the capacity of the person or system first asked to meet it.

You will surely wither, both you and this people with you, for this word is too heavy for you; you are not able to do it alone.
Exodus 18:18 · SDVThe burden exceeds one person’s capacity, and the limit is stated directly.
The one without strength answered him, Sir, I have no one to throw me into the pool when the waters are stirred; while I am coming, another steps down before me.
John 5:7 · SDVHis need is real, but he lacks someone to help him reach the pool.
Not that we are enough on our own to count anything as from ourselves, but our capacity is from God.
2 Corinthians 3:5 · SDVHuman sufficiency is named as limited, with capacity traced beyond the self.
And wherever it seizes him, it throws him down, and he foams and grinds his teeth and withers. And I spoke to your disciples that they should throw it out, and they could not.
Mark 9:18 · SDV

Mark uses the same Greek verb-family for “could not”: ⁨οὐκ ἠδυνήθησαν⁩ (ouk ēdynēthēsan, they were not able). The repeated wording keeps the disciples’ inability visible at the center of the father’s appeal.
