Matthew 17:19-21

19 Then the disciples came to Jesus privately and said, “Why could we not cast it out?”

20 So Jesus said to them, “Because of your [b]unbelief; for assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you. 21 [c]However, this kind does not go out except by prayer and fasting.”
