13 I tell you that Elijah has already come. And people did to him whatever they wanted to do. The Scriptures said this would happen to him.”
14 Then Jesus, Peter, James, and John went to the other followers. They saw a great crowd around them. The teachers of the law were arguing with them.
15 But when the crowd saw Jesus, they were surprised and ran to welcome him.
16 Jesus asked, “What are you arguing about with the teachers of the law?”
17 A man answered, “Teacher, I brought my son to you. He has a spirit from the devil in him. This spirit stops him from talking.
18 The spirit attacks him and throws him on the ground. My son foams at the mouth, grinds his teeth, and becomes very stiff. I asked your followers to force the evil spirit out, but they couldn’t.”
19 Jesus answered, “You people don’t believe! How long must I stay with you? How long must I go on being patient with you? Bring the boy to me!”
