The illustrations of the fountain and the fig-tree are among the touches which, if they do not indicate one who is familiar with Palestine, at any rate agree well with the fact that the writer of this Epistle was such. Springs tainted with salt or with sulphur are not rare, and it is stated that most of those on the eastern slope of the hill-country of Judæa are brackish. The fig-tree, the vine, and the olive were abundant throughout the whole country; and St. James, if he looked out of window as he was writing, would be likely enough to see all three. It is not improbable that in one or more of the illustrations he is following some ancient saying or proverb. Thus, Arrian, the pupil of Epictetus, writing less than a century later, asks, "How can a vine grow, not vinewise, but olivewise, or an olive, on the other hand, not olivewise, but vinewise? It is impossible, inconceivable." It is possible that our Lord Himself, when He used a similar illustration in connexion with the worst of all sins of the tongue, was adapting a proverb already in use. In speaking of "the blasphemy against the Spirit" He says, "Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt: for the tree is known by its fruit. Ye offspring of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh. The good man out of his good treasure bringeth forth good things; and the evil man out of his evil treasure bringeth forth evil things. And I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment" (Matt. xii. 33-36). And previously, in the Sermon on the Mount, where He is speaking of deeds rather than of words, "By their fruits ye shall know them. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit, but the corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit" (Matt. vii. 16-18).
