I brought him to thy disciples. He had come with the multitude, hoping to find Jesus, and, being disappointed, he had applied to the nine to relieve his misery. When the apostles were sent forth with commission to heal the sick, they returned with joy to report the success of their tour: they cast forth many devils; they noted with glad surprise that the very demons were subject to them in the Name of Jesus (Matthew 10:1; Luke 10:17).
It was different now. They could not cure him. What means they used we know not; at any rate, they were ineffectual. The writers who record the failure must be allowed to be truthful and honest. There had been much to depress these disciples.
Their Master was absent, gone they knew not whither; how long he would be away they could not tell; the boldest and most trusted of their company were no longer present to cheer them with sympathy, to repel attacks, to stand forth as champions.
The scribes' uncompromising disbelief (Mark 9:16) had for the moment obscured their own perfect trust; the atmosphere of infidelity had affected their own breathing; the memory of Christ's words concerning his Passion and death recurred again with dispiriting effect, infusing doubt and disquiet; they bad for the time lost the ardour and confidence which had animated them in their first mission; retaining belief in Christ's claims, they felt a hesitation concerning their own ability; and the conscious weakness in their exorcism nullified its power, and they could do no mighty work.
