SEV Biblia, Chapter 17:19
Entonces, llegndose los discípulos a Jess, aparte, dijeron: ¿Por qu nosotros no lo pudimos echar fuera?
Clarke's Bible Commentary - Matthew 17:19
Verse 19. Why could not we cast him out?] They were confounded at their want of success-but not at their want of faith, which was the cause of their miscarriage! When the ministers of the Gospel find their endeavours, with respect to some places or persons, ineffectual, they should come, by private prayer, to Christ, humble themselves before him, and beg to be informed whether some evil in themselves have not been the cause of the unfruitfulness of their labours.
John Gill's Bible Commentary
Ver. 19. Then came the disciples to Jesus apart , etc.] Or secretly, as the Vulgate Latin, and Munsters Hebrew Gospel read; that is, privately, and when alone; and as Mark says, when he was come into the house; and was by himself, then came the nine disciples to him, to converse with him about this matter, and said unto him, why could not we cast him out ? That is, the devil, and so cure the lunatic; the Syriac and Persic versions render it, why could not we heal him? The lunatic; which only could be done by casting out the demon: they were concerned, fearing they had lost the power which Christ had bestowed on them, and wanted to know what they had done, which had deprived them of it; and what should be the cause of their late unsuccessful attempt, when they had so frequently triumphed over the unclean spirits, that were subject to them. Though they might have learned from the answer Christ gave to the father of the lunatic, and the general character of the Jewish nations in that answer, the true reason of their own inability; but this they took no notice of, imagining it belonged entirely to others, and not to them.
Matthew Henry Commentary
Verses 14-21 - The case of afflicted children should be presented to God by faithfu and fervent prayer. Christ cured the child. Though the people wer perverse, and Christ was provoked, yet care was taken of the child When all other helps and succours fail, we are welcome to Christ, ma trust in him, and in his power and goodness. See here an emblem of Christ's undertaking as our Redeemer. It encourages parents to brin children to Christ, whose souls are under Satan's power; he is able to heal them, and as willing as he is able. Not only bring them to Chris by prayer, but bring them to the word of Christ; to means by whic Satan's strong-holds in the soul are beaten down. It is good for us to distrust ourselves and our own strength; but it is displeasing to Christ when we distrust any power derived from him, or granted by him There was also something in the malady which rendered the cur difficult. The extraordinary power of Satan must not discourage ou faith, but quicken us to more earnestness in praying to God for the increase of it. Do we wonder to see Satan's bodily possession of thi young man from a child, when we see his spiritual possession of ever son of Adam from the fall!
