Matthew Poole's Concise Commentary
Matthew 17:16
Ver. 14-16. The same history is told us both by Mark and Luke, but with considerable difference; we have it, Mark 9:17,18, thus, And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit; and wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out, and they could not. As an introduction to this, Mark saith, Mark 9:14, that when our Saviour came to his disciples, he saw a great multitude about them, and the scribes questioning with them. And straightway all the people, when they beheld him, were greatly amazed, and running to him saluted him. And he asked the scribes, What question ye with them? Luke gives us this account, Luke 9:37, And it came to pass, that on the next day, when they were come down from the hill, much people met him. And, behold, a man of the company cried out, saying, Master, I beseech thee, look upon my son: for he is mine only child. And, lo, a spirit taketh him, and he suddenly crieth out; and it teareth him that he foameth again, and bruising him hardly departeth from him. And I besought thy disciples to cast him out; and they could not. When our Lord went up to the mountain where he was transfigured, he left at the foot of it the multitudes, and nine of his apostles, he took only three with him. How long he stayed there no evangelist tells us. The multitude and his disciples stayed waiting for his coming, probably not far of; some of the scribes were got to them, and they were arguing together. The day after our Lord, and Peter, James, and John, were come down from the mount, they go to the multitude, who received him with great passion, and saluted him. He begins to inquire what they were discoursing about; but was by and by interrupted with a certain man, who comes and falls down upon his knees before him, begging mercy for his son, who (as Matthew reports his condition) was lunatic and sore vexed, often falling into the fire, and often into the water. Mark saith, he had a dumb spirit, that it tore him, he often foamed and gnashed with his teeth. Luke saith, that it was the man's only child, that he had a spirit, that he cried out, it tare him, he foamed, and was bruised by it, &c. By the description of this young man's disease, it appeareth to have been what we call the falling sickness, wherein men fall down, foam, and beat themselves. With this disease the devil joined, so as at certain times of the moon this disease took him, and the devil acting with it, he was dumb, at least for the time, and fell sometimes into the fire, sometimes into the water, foamed, gnashed with his teeth, tore himself: this seems to have been his condition. The father (during Christ's absence) had attempted a cure by his disciples, but the text saith they could not (the reason we shall hear afterward); upon this he crieth unto Christ for his help.
