Mark 9:14-22

When they came [back] to the [other nine] disciples, they saw a large crowd around them, and scribes questioning and arguing with them. [Matt 17:14-18; Luke 9:37-42] Immediately, when the entire crowd saw Jesus, they were startled and began running up to greet Him. He asked them, “What are you discussing with them?” One of the crowd replied to Him, “Teacher, I brought You my son, possessed with a spirit which makes him unable to speak; and whenever it seizes him [intending to do harm], it throws him down, and he foams [at the mouth], and grinds his teeth and becomes stiff. I told Your disciples to drive it out, and they could not do it.” He replied, “O unbelieving (faithless) generation, how long shall I be with you? How long shall I put up with you? Bring him to Me!” They brought the boy to Him. When the [demonic] spirit saw Him, immediately it threw the boy into a convulsion, and falling to the ground he began rolling around and foaming at the mouth. Jesus asked his father, “How long has this been happening to him?” And he answered, “Since childhood. The demon has often thrown him both into fire and into water, intending to kill him. But if You can do anything, take pity on us and help us!”
