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, when it was whole it was meet for no work,.... Before it was cut into pieces, and east into the fire, it was not fit to make so much as a pin of to hang anything on; so Israel, when all together, before the ten tribes were carried captive, or the Jews before the captivity of Jeconiah, were useless and unfruitful, and to every good work reprobate:

how much less shall it be meet yet for any work when the fire hath devoured it, and it is burned? as its wood is good for nothing before it is burned, its ashes are useless after.
