Mark 9:13-23

13 But I say to you, That also Elijah hath come, and they did to him what they willed, as it hath been written of him.'
14 And having come unto the disciples, he saw a great multitude about them, and scribes questioning with them,
15 and immediately, all the multitude having seen him, were amazed, and running near, were saluting him.
16 And he questioned the scribes, `What dispute ye with them?'
17 and one out of the multitude answering said, `Teacher, I brought my son unto thee, having a dumb spirit;
18 and wherever it doth seize him, it doth tear him, and he foameth, and gnasheth his teeth, and pineth away; and I spake to thy disciples that they may cast it out, and they were not able.'
19 And he answering him, said, `O generation unbelieving, till when shall I be with you? till when shall I suffer you? bring him unto me;'
20 and they brought him unto him, and he having seen him, immediately the spirit tare him, and he, having fallen upon the earth, was wallowing -- foaming.
21 And he questioned his father, `How long time is it since this came to him?' and he said, `From childhood,
22 and many times also it cast him into fire, and into water, that it might destroy him; but if thou art able to do anything, help us, having compassion on us.'
23 And Jesus said to him, `If thou art able to believe! all things are possible to the one that is believing;'
