Luke 17:6

Sea - Large basin.

As a grain of mustard seed - A faith that increases and thrives as that is described to do, Matthew 13:32 (note), where see the note. See also Matthew 17:20.

This sycamine - The words seem to intimate that they were standing by such a tree. The sycamine is probably the same as the sycamore. Sycamore with us, says Mr. Evelyn, is falsely so called, being our acer majus, greater maple. The true sycamore is the ficus Pharaonis or Aegyptia, Pharaoh's, or Egyptian fig-tree; called also, from its similitude in leaves and fruit, morosyous, or mulberry fig-tree. The Arabians call it guimez: it grows in Cyprus, Caria, Rhodes, and in Judea and Galilee, where our Lord at this time was: see Luke 17:11. St. Jerome, who was well acquainted with these countries, translates the word mulberry-tree.

Be thou plucked up by the root - See the note on Matthew 21:21, where it is shown that this mode of speech refers to the accomplishment of things very difficult, but not impossible.

See Matthew 17:20. "Sycamine-tree." This name, as well as sycamore, is given, among us, to the large tree commonly called the buttonwood; but the tree here mentioned is different. The Latin Vulgate and the Syriac versions translate it "mulberry-tree." It is said to have been a tree that commonly grew in Egypt, of the size and appearance of a mulberry-tree, but bearing a species of figs. This tree was common in Palestine. It is probable that our Lord was standing by one as he addressed these words to his disciples. Dr. Thomson ("The Land and the Book," vol. i. p. 22-24) says of this tree: "It is generally planted by the wayside, in the open space where several paths meet." (Compare Luke 19:4.) "This sycamore is a remarkable tree. It not only bears several crops of figs during the year, but these figs grow on short stems along the trunk and large branches, and not at the end of twigs, as in other fruit-bearing trees. The figs are small, and of a greenish-yellow color. At Gaza and Askelon I saw them of a purple tinge, and much larger than they are in this part of the country. They were carried to market in large quantities, and appeared to be more valued there than with us. Still, they are, at best, very insipid, and none but the poorer classes eat them. It is easily propagated, merely by planting a stout branch in the ground, and watering it until it has struck its roots into the soil. This it does with great rapidity and to a vast depth. It was with reference to this latter fact that our Lord selected it to illustrate the power of faith.

Now, look at this tree - its ample girth, its wide-spread arms branching off from the parent trunk only a few feet from the ground; then examine its enormous roots, as thick, as numerous, and as wide-spread into the deep soil below as the branches extend into the air above the very best type of invincible steadfastness. What power on earth can pluck up such a tree? Heaven's thunderbolt may strike it down, the wild tornado may tear it to fragments, but nothing short of miraculous power can fairly pluck it up by the roots."

17:6 And he said, If ye had faith as a grain of mustard seed - If ye had the least measure of true faith, no instance of duty would be too hard for you. Ye would say to this sycamine tree - This seems to have been a kind of proverbial expression.
