common metaphor to express intellectual or spiritual ability. St. Paul speaks of faith that would "move mountains;" and you will find in Lightfoot's Horae Hebraicae (ii. p. 285), "There was not such another rooter up of mountains as Ben Azzai." Now we know from St. Luke's Gospel (xvii. 6), that Jesus used a similar metaphor of trees, as well as of mountains, to exemplify the power of faith; and this without any reference to "something done and done miraculously:" "If ye have faith as a grain of mustard seed, ye would say unto this sycamine tree, Be thou rooted up and planted in the sea; and it would have obeyed." Planted in the sea! Can you dream that so preposterous a portent could have been prayed for by any sane and sober follower of Christ in compliance with his Master's suggestion? Bear in mind that these words in St. Luke's Gospel were uttered a long time before the blasting of the fig-tree is supposed to have happened, and at a different place. Does not then a comparison of this passage with the other two make it probable that Jesus was in the habit of encouraging His disciples to be "pluckers up of mountains" and "rooters up of trees," not literally but metaphorically, meaning thereby that they were to attempt and accomplish the greatest feats of faith?

He had told the disciples they must forgive "till seventy times seven." The Apostles, in despair, replied "Increase our faith:" and then Jesus tells them that if they had but a germ of living trust, they could become "uprooters of sycamine trees," in other words they could perform for-
