(6) If ye had faith as a grain of mustard seed.--The words remind us, and must have reminded the disciples, of those of Matthew 17:20, which were called forth by the failure of the disciples to heal the demoniac boy after the Transfiguration. The "sycamine tree" (probably not the same as the "sycamore," but identified by most botanists with the mulberry tree, still cultivated on the slopes of the Lebanon and in the neighbourhood of Jerusalem and Nablous, both for its fruit and as supplying food for silkworms) takes the place of "this mountain," sc. Hermon, as an illustration of what true faith could do. If we suppose the conversation to have taken place near the Sea of Galilee, both features of the comparison gain a local vividness. It is remarkable that our Lord meets the prayer with what sounds like a reproof; and such a reproof, we must believe, was needed. The most elementary faith would have been enough to teach them (assuming the connection that has been traced above) that God is love, and that He would help them to overcome all hindrances to their love being after the pattern of His own. There was something, it may be, false in the ring of that prayer, an unreal diffidence asking for that as a gift which really comes only through active obedience and the experience which is gained through it.

Verse 6. - And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you. The Lord signifies that a very slight real faith, which he compares to the mustard seed, that smallest of grains, would be of power sufficient to accomplish what seemed to them impossible. In other words, he says, "If you have any real faith at all, you will be able to win the victory over yourselves necessary for a perpetual loving judgment of others." The sycamine tree here mentioned in his comparison is not the sycamore; he was probably standing close by the tree in question as he spoke. The sycamine is the black mulberry, Morns nigra, still called sycamenea in Greece.

17:1-10 It is no abatement of their guilt by whom an offence comes, nor will it lessen their punishment that offences will come. Faith in God's pardoning mercy, will enable us to get over the greatest difficulties in the way of forgiving our brethren. As with God nothing is impossible, so all things are possible to him that can believe. Our Lord showed his disciples their need of deep humility. The Lord has such a property in every creature, as no man can have in another; he cannot be in debt to them for their services, nor do they deserve any return from him.And the Lord said,.... In answer to the disciples. The Syriac version leaves out the word "Lord": and the Persic version, in the room of it reads, "Jesus":

if ye had faith as a grain of mustard seed; See Gill on Matthew 17:20.

ye might say unto this sycamine tree; which was near at hand; for in Galilee, where Christ now was, such trees grew, especially in lower Galilee: hence those words (u);

"from Caphar-Hananiah, and upwards, all the land which does not bear "sycamines", is upper Galilee, and from Caphar-Hananiah, and downwards, all which does bear "sycamines", is lower Galilee.''

This, by Maimonides (w), is said to be a wild fig tree; but the Vulgate Latin, Syriac, Arabic, and Ethiopic versions render it, the "mulberry tree": and that the sycamine and mulberry tree are the same, Beza shows from Dioscorides, Athenaeus, and Galen; though whether it is the same with the sycamore in Luke 19:4 is not certain. The first of these writers makes them to be the same; and the last asserts they are different, and so they should seem by their different names.

Be thou plucked up by the root, and be thou planted in the sea, and it should obey you: for such a tree to be plucked up by the root at a word speaking, is very wonderful and miraculous, and beyond the power of nature; and much more for it to remove into the sea, and plant itself there, where trees grow not; and to believe this should be done, and such a word of command obeyed, one should think required very great faith; and yet, if it was but as a grain of mustard seed, which is very small, it might be done. The design is to show, what great things are done by faith, and what an increase of it they should have.
