16 "I brought him to Your disciples, and they could not cure him."

17 And Jesus answered and said, "You unbelieving and perverted generation, how long shall I be with you? How long shall I put up with you? Bring him here to Me."

20 And He said to them, "Because of the littleness of your faith; for truly I say to you, aif you have faith the size of ba mustard seed, you will say to cthis mountain, 'Move from here to there,' and it will move; and dnothing will be impossible to you.

21 ["aBut this kind does not go out except by prayer and fasting."]
