Matthew 17:18 DBY

¹⁶  And I brought him to thy disciples, and they were not able to heal him.

¹⁷  And Jesus answering said, O unbelieving and perverted generation, how long shall I be with you? how long shall I bear with you? Bring him here to me.

¹⁸  And Jesus rebuked him, and the demon went out from him, and the boy was healed from that hour.

¹⁹  Then the disciples, coming to Jesus apart, said [to him], Why were not *we* able to cast him out?

²⁰  And he says to them, Because of your unbelief; for verily I say unto you, If ye have faith as a grain of mustard [seed], ye shall say to this mountain, Be transported hence there, and it shall transport itself; and nothing shall be impossible to you.
