Matthew 17:17-19

International Standard Version

¹⁷ Jesus replied, “You unbelieving and perverted generation! How long must I be with you? How long must I put up with you? Bring him here to me!” ¹⁸ Then Jesus rebuked the demon and it came out of him, and the boy was healed that very hour.

¹⁹ Then the disciples came to Jesus privately and asked, “Why couldn’t we drive it out?”
