Mark 9:18-22

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.

He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.

And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.

And he asked his father, How long is it ago since this came unto him? And he said, Of a child.

And ofttimes it hath cast him into the fire, and into the waters, to destroy him: but if thou canst do any thing, have compassion on us, and help us.
