Verses 1-5 Shechaniah owned the national guilt. The case is sad, but it is not desperate; the disease threatening, but not incurable. Now that the people begin to lament, a spirit of repentance seems to be poured out; now there is hope that God will forgive, and have mercy. The sin that rightly troubles us, shall not ruin us. In melancholy times we must observe what makes for us, as well as against us. And there may be good hopes through grace, even where there is the sense of great guilt before God. The case is plain; what has been done amiss, must be undone again as far as possible; nothing less than this is true repentance. Sin must be put away, with a resolution never to have any thing more to do with it. What has been unjustly got, must be restored. Arise, be of good courage. Weeping, in this case, is good, but reforming is better. As to being unequally yoked with unbelievers, such marriages, it is certain, are sinful, and ought not to be made; but now they are not null, as they were before the gospel did away the separation between Jews and Gentiles.
Verses 6-14 There is hope concerning people, when they are convinced, not only that it is good to part with their sins, but that it is necessary; we must do it, or we are undone. So rich is the mercy, and so plenteous the redemption of God, that there is hope for the vilest who hear the gospel, and are willing to accept of free salvation. When sinners mourn for their sins, and tremble at the word of God, there is hope that they will forsake them. To affect others with godly sorrow or love to God, we must ourselves be affected. It was carefully agreed how this affair should be carried on. That which is hastily resolved on seldom proves lasting.
Verses 15-44 The best reformers can but do their endeavour; when the Redeemer himself shall come to Zion, he shall effectually turn away ungodliness from Jacob. And when sin is repented of and forsaken, God will forgive it; but the blood of Christ, our Sin-offering, is the only atonement which takes away our guilt. No seeming repentance or amendment will benefit those who reject Him, for self-dependence proves them still unhumbled. All the names written in the book of life, are those of penitent sinners, not of self-righteous persons, who think they have no need of repentance.
