[Verse] 23 I tell you the truth. Anyone who says to a mountain, 'move out of my way and jump into the sea,' and has no doubts in his soul but believes it will come to pass, that man's words will become true. [Analysis] This is the origin of the phrase "faith that can move mountains." [King James Version] 
For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.
Mark 9-16 (Translated) - Conservapedia
King James Version
