Mark 9:19-21

King James Version

¹⁹ He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.

²⁰ And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.

²¹ And he asked his father, How long is it ago since this came unto him? And he said, Of a child.
