Matthew‬ ‭17‬:‭19-20‬

Then the followers came to Jesus alone. They said, “We tried to force the demon out of the boy, but we could not. Why were we not able to make the demon go out?” Jesus answered, “You were not able to make the demon go out, because your faith is too small. Believe me when I tell you, if your faith is only as big as a mustard seed you can say to this mountain, ‘Move from here to there,’ and it will move. You will be able to do anything.” (‭Matthew‬ ‭17‬:‭19-20‬ ERV)
