Mark 9:27 WBT

²⁵  When Jesus saw that the people came running together, he rebuked the foul spirit, saying to him, [Thou] dumb and deaf spirit, I charge thee, come out of him, and enter no more into him.

²⁶  And [the spirit] cried, and rent him severely, and came out of him: and he was as one dead; so that many said, He is dead.

²⁷  But Jesus took him by the hand, and lifted him up; and he arose.

²⁸  And when he had come into the house, his disciples asked him privately, Why could not we cast him out?

²⁹  And he said to them, This kind can come forth by nothing, but by prayer and fasting.
