Mark 9:17-19

New Matthew Bible

¹⁷ A man from the crowd answered and said, Teacher, I have brought my son to you, who has a dumb spirit, ¹⁸ and whenever it takes him, it tears him, and he foams and gnashes with his teeth, and collapses. And I spoke to your disciples, to cast it out, but they could not.

¹⁹ Jesus answered him and said, O generation without faith, how long shall I be with you? How long shall I suffer you? Bring him to me.
