Mark 9:23

20 And they brought him to him. And seeing him the spirit immediately tore him; and falling upon the earth he rolled foaming.

21 And he asked his father, How long a time is it that it has been like this with him? And he said, From childhood;

22 and often it has cast him both into fire and into waters that it might destroy him: but if thou couldst [do] anything, be moved with pity on us, and help us.

23 And Jesus said to him, The 'if thou couldst' is [if thou couldst] believe: all things are possible to him that believes.

24 And immediately the father of the young child crying out said [with tears], I believe, help mine unbelief.

25 But Jesus, seeing that [the] crowd was running up together, rebuked the unclean spirit, saying to him, Thou dumb and deaf spirit, I command thee, come out of him, and enter no more into him.

26 And having cried out and torn [him] much, he came out; and he became as if dead, so that the most said, He is dead.
