(8) He.--Emphatic. He and only He. The redemption must not be limited to the consequences of iniquity, though including these. The psalm belongs to the age of true national contrition, when nothing would satisfy but deliverance from sin, as well as from its punishment. This appears decisively from a comparison with Psalm 25:22, where the expression is "from all his troubles." Thus, this psalm was prepared to be what it has become, one of the penitential psalms of the world.
130:5-8 It is for the Lord that my soul waits, for the gifts of his grace, and the working of his power. We must hope for that only which he has promised in his word. Like those who wish to see the dawn, being very desirous that light would come long before day; but still more earnestly does a good man long for the tokens of God's favour, and the visits of his grace. Let all that devote themselves to the Lord, cheerfully stay themselves on him. This redemption is redemption from all sin. Jesus Christ saves his people from their sins, both from the condemning and from the commanding power of sin. It is plenteous redemption; there is an all-sufficient fulness in the Redeemer, enough for all, enough for each; therefore enough for me, says the believer. Redemption from sin includes redemption from all other evils, therefore it is a plenteous redemption, through the atoning blood of Jesus, who shall redeem his people from all their sins. All that wait on God for mercy and grace, are sure to have peace.
And he shall redeem Israel from all his iniquities. The Lord shall do it; in whom Israel is encouraged to hope; with whom grace and redemption were; or who was appointed to be the Redeemer. Redemption was then future, when these words were said, but certain, by the promise of God and agreement of Christ; and would be of the whole Israel, or elect of God; and that from "all" their iniquities, original and actual; sins, secret and open, of heart, lip, and life: and which is no small encouragement for Israel to hope in the Lord, for the sake of which this is added; as well as for the further illustration of the nature of redemption by Christ; which is complete, and now obtained, and is an eternal one.
