"And when they were
come to the multitude,
there came to him a
certain man, kneeling
down
to him, and saying,
Lord, have mercy on
my
son; for he is lunatic,
and sore vexed.
And I brought him to thy disciples, and they
could not cure him.
Then Jesus answered and ssid, O faithless and
perverse generation, how long shall I be with
you? how long shall I suffer you?
bring him hither to me. And Jesus rebuked the
devil; and he departed out of him: and the child
was cured from that very hour"
Matthew 17:14-18
