Mark 9:14-27

Verse 15

Were greatly amazed - Probably, because he came so unexpectedly; but the cause of this amazement is not self-evident.
Verse 17

A dumb spirit - That is, a demon who afflicted those in whom it dwelt with an incapacity of speaking. The spirit itself could not be either deaf or dumb. These are accidents that belong only to organized animate bodies. See this case explained, Mat 17:14 (note), etc.
Verse 18

Pineth away - By these continual torments; so he was not only deaf and dumb, but sorely tortured besides.
Verse 20

When he saw him the spirit tare him; and he fell on the ground, etc. - When this demon saw Jesus, he had great rage, knowing that his time was short; and hence the extraordinary convulsions mentioned above.
Verse 22

If Thou canst Do any thing - I have already tried thy disciples, and find they can do nothing in this case; but if thou hast any power, in mercy use it in our behalf.
Verse 23

If Thou canst Believe - This was an answer to the inquiry above. I can furnish a sufficiency of power, if thou canst but bring faith to receive it. Why are not our souls completely healed? Why is not every demon cast out? Why are not pride, self-will, love of the world, lust, anger, peevishness, with all the other bad tempers and dispositions which constitute the mind of Satan, entirely destroyed? Alas! it is because we do not believe; Jesus is able; more, Jesus is willing; but we are not willing to give up our idols; we give not credence to his word; therefore hath sin a being in us, and dominion over us.
Verse 24

Lord, I believe - The word Lord is omitted by ABCDL, both the Syriac, both the Arabic later Persic, Ethiopic, Gothic, and three copies of the Itala. Griesbach leaves it out. The omission, I think, is proper, because it is evident the man did not know our Lord, and therefore could not be expected to accost him with a title expressive of that authority which he doubted whether he possessed, unless we grant that he used the word κυριε after the Roman custom, for Sir.

Help thou mine unbelief - That is, assist me against it. Give me a power to believe.
Verse 25

I charge thee - Considerable emphasis should be laid on the pronoun: - Thou didst resist the command of my disciples, now I command thee to come out. If this had been only a natural disease, for instance the epilepsy, as some have argued, could our Lord have addressed it, with any propriety, as he has done here: Thou deaf and dumb spirit, come out of him, and enter no more into him? Is the doctrine of demoniacal influence false? If so, Jesus took the most direct method to perpetuate the belief of that falsity, by accommodating himself so completely to the deceived vulgar. But this was impossible; therefore the doctrine of demoniacal influence is a true doctrine, otherwise Christ would never have given it the least countenance or support.
