when Jesus, Peter, yakobus and yohanes back to the other disciples, they saw a large crowd gathered around the disciples, and some scribes were questioning something with them. when the crowd saw Jesus, they were all amazed and rushed to greet him. then Jesus said to them: "what you asked to them?" said one from the crowd: "teacher, I brought my son to you, because he possessed bad spirit and silencing him. and whenever the spirit strikes him, the spirit slams the child into ground: and foaming at the mouth, teeth make noise and body go into spasm, I've ask your disciples, but they can not cast it. " Jesus then said to them: "O you who do not believe, how much longer I have live among you? how much longer I have to pation with you? bring him here!"
then they took him. when the spirit saw Jesus, the child was immediately shaken by the bad spirit, and the child was thrown to the ground and rolled, foaming at the mouth. then Jesus asked his parent: "how long she suffered this?" he replied: "since his childhood. and often the spirit is dragged him into the fire or into water to destroy it. So if you can do something, please help us and have mercy on us." Jesus replied: "you say: if you can? nothing is impossible for those who believe!" soon the parent shouted: "I believe, help me who do not believe!" when Jesus saw the crowds had gathered more and more, he rebuked the unclean spirit, jesus said: "O you spirits that cause people to become deaf and dumb, I command you, to out from this child and do not enter him again!" then the spirit is crying out and shaken the boy with the great. the boy looks like a dead man, so many people who say: "he is dead." but Jesus held his hand and woke him, and he got up himself.
when Jesus was at home, and his students alone with him, them ask, why we are not able to cast out it? "he said to them:" This bad spirit can not be expelled except by prayer.
