Mark 9:18-20

Living Bible

¹⁸ And whenever the demon is in control of him it dashes him to the ground and makes him foam at the mouth and grind his teeth and become rigid.^[a] So I begged your disciples to cast out the demon, but they couldn’t do it.”

¹⁹ Jesus said to his disciples,^[b] “Oh, what tiny faith you have; how much longer must I be with you until you believe? How much longer must I be patient with you? Bring the boy to me.”

²⁰ So they brought the boy, but when he saw Jesus, the demon convulsed the child horribly, and he fell to the ground writhing and foaming at the mouth.
