If I speak in the tongues of mortals and of angels, but do not have love, I am a noisy gong or a clanging cymbal. 2 And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but do not have love, I am nothing. 3 If I give away all my possessions, and if I hand over my body so that I may boast, but do not have love, I gain nothing.
Jesus answered them, "Have faith in God. 23 Truly I tell you, if you say to this mountain, 'Be taken up and thrown into the sea,' and if you do not doubt in your heart, but believe that what you say will come to pass, it will be done for you.
= Matt 21:21
Jesus answered them, "Truly I tell you, if you have faith and do not doubt, not only will you do what has been done to the fig tree, but even if you say to this mountain, 'Be lifted up and thrown into the sea,' it will be done.
Thom 48 and 106
48 Jesus said, "If two make peace with each other in a single house, they will say to the mountain, 'Move from here!' and it will move." [Complete Gospels]
106 Jesus said, "When you make the two into one, you will become children of Adam, 2 and when you say, 'Mountain, move from here!' it will move." [Complete Gospels]
Lachs, [Rabbinic Commentary on the New Testament] notes:
For the feat of removing a mountain from its place, the rabbinic expression is oqer barim, and it is used to express the idea of doing the near impossible, as here. Miraculously moving a tree from its place, Luke 17.6, is mentioned in rabbinic literature: “May this carob tree be moved, and it was.” [B. BM 58b]
