(9) By this therefore shall the iniquity of Jacob be purged.--The pronoun may refer either to the chastisement of the previous verse as the instrument of purification (preferably), or to the destruction of idols which follows as the result and proof of that purification, the end contemplated by Jehovah in His chastisements.

This is all the fruit to take away his sin.--Better, of taking away his sin. The words repeat the thought of the previous clause. The fruit of repentance and forgiveness will be found in rooting out all vestiges of idol-worship. The LXX., "when I shall take away their sins," is quoted by St. Paul in Romans 11:27.

The groves and images.--Literally, as elsewhere, the Asherahs, or the sun-images, the two leading features of the cultus which Israel had borrowed from the Ph?nicians. In the action of Josiah (2Chronicles 34:3-4) we may, with little doubt, trace a conscious endeavour to fulfil the condition which Isaiah had thus proclaimed. He sought to "purge" Judah and Jerusalem from the "groves and the carved (sun) images, and molten images."

Verse 9. - By this; i.e. "by the punishment inflicted." God accepts punishment as an expiation of sin; and this punishment of Judah was especially intended to be expiatory, and to remove at once his guilt, and the evil temper which had led him into sin. Its fruit would be a revulsion from idolatry, which would show itself in a fierce determination to destroy all idolatrous emblems and implements, altars, groves, images, and the like. This spirit was strongly shown in the Maccabee period (see 1 Macc. 5:44, 68 1 Macc. 10:84 1 Macc. 13:47, etc.). He maketh all the stones of the altar as chalkstones. A calcining of the stones into lime is probably intended. It was usual to subject the idolatrous objects to the action of fire, and then to stamp them into powder (2 Kings 23:4, 6, 11, 12, 15, etc.). The groves and images (comp. 1 Kings 15:13; 1 Kings 16:33; 2 Kings 17:10; 2 Chronicles 14:3; and see the comment on Isaiah 17:8).

27:6-13 In the days of the gospel, the latter days, the gospel church shall be more firmly fixed than the Jewish church, and shall spread further. May our souls be continually watered and kept, that we may abound in the fruits of the Spirit, in all goodness, righteousness, and truth. The Jews yet are kept a separate and a numerous people; they have not been rooted out as those who slew them. The condition of that nation, through so many ages, forms a certain proof of the Divine origin of the Scriptures; and the Jews live amongst us, a continued warning against sin. But though winds are ever so rough, ever so high, God can say to them, Peace, be still. And though God will afflict his people, yet he will make their afflictions to work for the good of their souls. According to this promise, since the captivity in Babylon, no people have shown such hatred to idols and idolatry as the Jews. And to all God's people, the design of affliction is to part between them and sin. The affliction has done us good, when we keep at a distance from the occasions of sin, and use care that we may not be tempted to it. Jerusalem had been defended by grace and the Divine protection; but when God withdrew, she was left like a wilderness. This has awfully come to pass. And this is a figure of the deplorable state of the vineyard, the church, when it brought forth wild grapes. Sinners flatter themselves they shall not be dealt with severely, because God is merciful, and is their Maker. We see how weak those pleas will be. Verses 12,13, seem to predict the restoration of the Jews after the Babylonish captivity, and their recovery from their present dispersion. This is further applicable to the preaching of the gospel, by which sinners are gathered into the grace of God; the gospel proclaims the acceptable year of the Lord. Those gathered by the sounding of the gospel trumpet, are brought in to worship God, and added to the church; and the last trumpet will gather the saints together.By this therefore shall the iniquity of Jacob be purged,.... Or "expiated", or "atoned" (a); not that afflictions are atonements for sin, or give satisfaction to divine justice for it; but they are the means of bringing the Lord's people to a sense of their sins, and to repentance and humiliation for them, and confession of them, and of leading them to the blood and sacrifice of Christ, by which they are expiated and atoned, and which the Spirit of God brings near, and applies unto them; whereby their sins, they are convicted of by means of afflictions, and which lay heavy upon their consciences, are purged away, and removed from them:

and this is all the fruit, to take away sin; this is the design and use of afflictions, the profit and advantage of them to the saints, that, being humbled for their sins, they depart from them, leave and forsake them; as well as the guilt of them is taken away from their consciences, through the application of pardoning grace, upon their repentance; see Job 36:8 this shows another difference between the afflictions of God's people and of others: namely, in the use and end of them. The sin of idolatry seems to be particularly designed by what follows; unless the sin of the present Jews, in their disbelief and rejection of the Messiah, should be rather intended; which, through their long affliction, they will be convinced of in the latter day, and it will be taken away from them, and be purged and expiated through the atoning sacrifice of Christ, the Saviour and Deliverer, they will embrace, Romans 11:25,

when he maketh all the stones of the altar as chalkstones that are beaten in sunder; that is, when Jacob, or the people of the Jews, being convinced of their idolatry by their afflictions, shall pull down all their idolatrous altars; perhaps particularly referring to that which Ahaz made, 2 Kings 16:10 and remove the stones thereof, and break them to pieces, as chalkstones for lime, which is easily done:

the groves and the images shall not stand up; erect, to be worshipped; but shall be thrown down, demolished, and broke to pieces; and, by thus abandoning their idols and idolatrous practices, they will show the sense they have of their sins, and the sincerity of their repentance; and it is to be observed, that the Jews, after their return from the Babylonish captivity, never practised idolatry more, not in the literal sense; perhaps some respect may be had here to the time when they shall look on him whom they have pierced, and mourn; and when they shall renounce all their legal sacrifices, traditions of the elders, and their own righteousness, their idols, and look alone to the sacrifice of Christ, and declare against all the idolatry of the church of Rome, and all antichristian worship.
