Mark 9:17-22

17Then one of the crowd answered and said, “Teacher, I brought You my son, who has a mute spirit.

18And wherever it seizes him, it throws him down; he foams at the mouth, gnashes his teeth, and becomes rigid. So I spoke to Your disciples, that they should cast it out, but they could not.”

19He answered him and said, “O faithless generation, how long shall I be with you? How long shall I bear with you? Bring him to Me.”

20Then they brought him to Him. And when he saw Him, immediately the spirit convulsed him, and he fell on the ground and wallowed, foaming at the mouth.

21So He asked his father, “How long has this been happening to him?” And he said, “From childhood.

22And often he has thrown him both into the fire and into the water to destroy him. But if You can do anything, have compassion on us and help us.”
