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 it out, but they were unable.” / After Jesus had gone into the house, His disciples asked Him privately, “Why couldn’t we drive it out?” / Jesus answered, “This kind cannot come out, except by prayer.”
