| Geneva Study Bible Son of man, What is the vine tree more than any tree, or than a branch which is among the {a} trees of the forest? (a) Which brings forth no fruit, no more than the other trees of the forest do: meaning that if Jerusalem, which bore the name of his Church, did not bring forth fruit it would be utterly destroyed. Wesley's Notes 15:2 The vine - tree - Israel is here compared to a vine, which, when fruitless, is utterly unprofitable. This the prophet minds them of to humble them, and awaken them to fruitfulness. A branch - One branch of a tree in the forest is of more use than the whole vine - tree is, except for its fruit. Jamieson-Fausset-Brown Bible Commentary 2, 3. What has the vine-wood to make it pre-eminent above other forest-wood? Nothing. Nay, the reverse. Other trees yield useful timber, but vine-wood is soft, brittle, crooked, and seldom large; not so much as a "pin" (the large wooden peg used inside houses in the East to hang household articles on, Isa 22:23-25) can be made of it. Its sole excellency is that it should bear fruit; when it does not bear fruit, it is not only not better, but inferior to other trees: so if God's people lose their distinctive excellency by not bearing fruits of righteousness, they are more unprofitable than the worldly (De 32:32), for they are the vine; the sole end of their being is to bear fruit to His glory (Ps 80:8, 9; Isa 5:1, &c.; Jer 2:21; Ho 10:1; Mt 21:33). In all respects, except in their being planted by God, the Jews were inferior to other nations, as Egypt, Babylon, &c., for example, in antiquity, extent of territory, resources, military power, attainments in arts and sciences. or than a branch-rather, in apposition with "the vine tree." Omit "or than." What superiority has the vine if it be but a branch among the trees of the forest, that is, if, as having no fruit, it lies cut down among other woods of trees? Matthew Henry's Concise Commentary 15:1-8 Jerusalem like an unfruitful vine. - If a vine be fruitful, it is valuable. But if not fruitful, it is worthless and useless, it is cast into the fire. Thus man is capable of yielding a precious fruit, in living to God; this is the sole end of his existence; and if he fails in this, he is of no use but to be destroyed. What blindness then attaches to those who live in the total neglect of God and of true religion! This similitude is applied to Jerusalem. Let us beware of an unfruitful profession. Let us come to Christ, and seek to abide in him, and to have his words abide in us. |
