Matthew 17:17

¹⁵  Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.

¹⁶  And I brought him to thy disciples, and they could not cure him.

¹⁷  Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me.

¹⁸  And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour.

¹⁹  Then came the disciples to Jesus apart, and said, Why could not we cast him out?
