23 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.
[AD 407] John Chrysostom on Mark 11:19-26
(non occ.) Or else, as He did not dry up the fig tree for its own sake, but for a sign that Jerusalem should come to destruction, in order to show His power, in the same way we must also understand the promise concerning the mountain, though a removal of this sort is not impossible with God.
