Marcos 9:18

18 Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth and becomes rigid. I asked your disciples to drive out the spirit, but they could not."

18 And wherever it takes him, it puts him down violently, streaming at the lips and twisted with pain; and his strength goes from him; and I made a request to your disciples to send it out, and they were not able.
