Matthew 17:19-21

New Matthew Bible

¹⁹ Then the disciples came to Jesus privately and asked, Why could we not cast him out? ²⁰ Jesus said to them, Because of your unbelief. For I say truly to you, if you had faith like a grain of mustard seed, you could say to this mountain, Move over there, and it would move; neither should anything be impossible for you to do. ²¹ However, this kind does not go out but by prayer and fasting.
