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.Behold, it is cast into the fire for fuel, That is; a vine tree when cut down, or a branch when cut off, it is good for nothing else; and that is the use it is generally put to; see John 15:6; and this, it is suggested, would be the end of the Jewish nation; who were become by their sins like a wild vine, and were fit fuel for the fire of divine wrath:

the fire devoureth both the ends of it; the branch cast into it, and so is quickly consumed. Kimchi explains this by Isaiah 9:12; "the Syrians before, and the Philistines behind, and they devour Israel with open mouth"; and Abendana of the ten tribes; but it seems only to design how soon the fire takes it; and how inevitable the consumption is when it is fired at both ends:

and the midst of it is burnt: presently; it being dried, and reduced to a brand by the heat of the fire at both ends: this Kimchi interprets of the city of Jerusalem, which was in the midst of the land:

is it meet for any work? no; for if it was not fit for any work when cut down, or cut off, much less when burnt in the fire.
