Mark 9:16

And when he 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 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.
