Mark 9:17-19

World English Bible

¹⁷ One of the multitude answered, “Teacher, I brought to you my son, who has a mute spirit; ¹⁸ and wherever it seizes him, it throws him down, and he foams at the mouth, and grinds his teeth, and wastes away. I asked your disciples to cast it out, and they weren’t able.”

¹⁹ He answered him, “Unbelieving generation, how long shall I be with you? How long shall I bear with you? Bring him to me.”
