Matthew 17:19-21

Revised Geneva Translation

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

²⁰ And Jesus said to them, “Because of your unbelief. For truly I say to you, if you have faith as much as is a grain of mustard seed, you shall say to this mountain, ‘Move from here to there’, and it shall move. And nothing shall be impossible to you.

²¹ “Nevertheless, this kind only goes out by prayer and fasting.”
