“And Jesus said to them, “Through your want of faith; for truly I say to you, if you may have faith as a grain of mustard, you will say to this mountain, Move from here to there, and it will move, and nothing will be impossible to you,”— Matthew 17:20 (LSV)
17And Jesus answering said, “O generation, unsteadfast and perverse, until when will I be with you? Until when will I bear you? Bring him to Me here”;

20And Jesus said to them, “Through your want of faith; for truly I say to you, if you may have faith as a grain of mustard, you will say to this mountain, Move from here to there, and it will move, and nothing will be impossible to you,
21[[and this kind does not go forth except in prayer and fasting.”]]
22And while they are living in Galilee, Jesus said to them, “The Son of Man is about to be delivered up into the hands of men,
23and they will kill Him, and the third day He will rise,” and they were exceedingly sorry.
