By this - This verse states the whole design of the punishment of the Jews. They were taken away from their temple, their city, and their land; they were removed from the groves and altars of idolatry by which they had been so often led into sin; and the design was to preserve them henceforward from relapsing into their accustomed idolatry.

The iniquity of Jacob - The sin of the Jewish people, and particularly their tendency to idolatry, which was their easily besetting sin.

Be purged - (see the note at Isaiah 1:25).

And this is all the fruit - And this is all the "object" or "design" of their captivity and removal to Babylon.

When he maketh all the stones of the altar as chalk stones - That is, Yahweh shall make the stones of the altars reared in honor of idols like chalk stones; or shall throw them down, and scatter them abroad like stones that are easily beaten to pieces. The sense is, that Yahweh, during their captivity in Babylon, would overthrow the places where they had worshipped idols.

The groves and images shall not stand up - The groves consecrated to idols, and the images erected therein (see the note at Isaiah 17:8).

The groves "And if the groves" - ולא velo. Four MSS., two ancient, of Kennicott's, and one ancient of my own, with the Septuagint; this makes a fuller sense.

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.

(a) "propitiabitur", Pagninus, Montanus; "expiabitur", Piscator.

He was angry, but not without love; He punished, but only to be able to pardon again. "Therefore will the guilt of Jacob be purged thus: and this is all the fruit of the removal of his son: when He maketh all altar-stones like chalk-stones that are broken in pieces, Astarte images and sun-pillars do not rise up again." With the word "therefore" (lâcēn) a conclusion is drawn from the expression "by measure." God punished Israel "by measure;" His punishment is a way to salvation: therefore it ceases as soon as its purpose is secured; and so would it cease now, if Israel would thoroughly renounce its sin, and, above all, the sin of all sins, namely idolatry. "Thus" (by this) refers to the בּשׂומו which follows; "by this," namely the breaking to pieces of the altars and images of the moon goddess; or possibly, to speak more correctly, the goddess of the morning-star, and those of the sun-god as well (see Isaiah 17:8). By the fact that Israel put away the fundamental cause of all mischief, viz., idolatry, the guilt for which it had yet to make atonement would be covered, made good, or wiped away (on cuppar, see at Isaiah 22:14). The parenthesis (cf., Isaiah 26:11) affirms that this very consequence would be all the fruit (cŏl-peri) desired by Jehovah of the removal of the sin of Israel, which the chastisement was intended to effect.

By this therefore shall the iniquity of Jacob be purged; and this is all the {i} fruit to take away his sin; when he maketh all the stones of the altar as chalkstones that are beaten asunder, the idols and images shall not stand up.

(i) He shows that there is no true repentance nor full reconciliation to God, till the heart is purged from all idolatry and the monuments of it are destroyed.

27:9 By this - By this manner of God's dealing with them. When - Which sin of Jacob's shall be purged, when he shall truly repent of all his sins, and especially of his idolatry. Altar - Their idolatrous altars. Possibly he may say the altar, with respect to that particular altar, which Ahaz had set upon the place of God's own altar; and this prophecy might be delivered in Ahaz's time, while that altar stood. Chalk - stones - When he shall break all those goodly altars in pieces. Not stand - Shall be thrown down with contempt.

images: or, sun images

9. By this-exile of Israel (the "sending away," Isa 27:8).

purged-expiated [Horsley].

all the fruit-This is the whole benefit designed to be brought about by the chastisement; namely, the removal of his (Israel's) sin (namely, object of idolatry; De 9:21; Ho 10:8).

when he-Jehovah; at the destruction of Jerusalem by Nebuchadnezzar, His instrument. The Jews ever since have abhorred idolatry (compare Isa 17:8).

not stand up-shall rise no more [Horsley].

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.
