Mark 9:20-22

20And they brought him to him: and when he saw him, immediately the spirit tore him; and he fell on the ground, and wallowed foaming. 21And he asked his father, How long is it since this came to him? And he said, From a child. 22And often 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.
