Matthew 17:20-21

World English Bible

²⁰ He said to them, “Because of your unbelief. For most certainly I tell you, if you have faith as a grain of mustard seed, you will tell this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you. ²¹ But this kind doesn’t go out except by prayer and fasting.” ^[a]
