23Jesus said unto him, If thou canst believe, all things are possible to him that believeth. 24And straightway the father of the child cried out, and said with tears, Lord, I believe; help thou mine unbelief. 25When Jesus saw that the people came running together, he rebuked the foul spirit, saying unto him, Thou dumb and deaf spirit, I charge thee, come out of him, and enter no more into him. 26And the spirit cried, and rent him sore, and came out of him: and he was as one dead; insomuch that many said, He is dead.27But Jesus took him by the hand, and lifted him up; and he arose. 28And when he was come into the house, his disciples asked him privately, Why could not we cast him out? 29And he said unto them, This kind can come forth by nothing, but by prayer and fasting.
