I will cleanse them - These promises of pardon and holiness must be referred to their state under the Gospel, when they shall have received Jesus as the promised Messiah.

And I will cleanse them from all their iniquity, whereby they have sinned against me,.... Even by the blood of Christ, which cleanses from all sin, of heart, lip, and life, in allusion to the purifications under the law, 1 John 1:7; see Ezekiel 36:25;

and I will pardon all their iniquities, whereby they have sinned, and whereby they have transgressed against me; for Christ's sake, and through his stoning sacrifice, and upon the foot of full satisfaction made by him. A heap of words is here used, to express the fulness of pardoning grace through the blood of Christ, which reaches to all manner of sin; and this is the great and peculiar blessing of the new covenant; see Jeremiah 31:34.

This prosperity gains stability and permanence through the people's being cleansed from their sins by their being forgiven, which, according to Jeremiah 31:34, will form the basis of the new covenant. Regarding the anomalous form לכול for לכל־ rof לכול mro, Hitzig supposes that in the scriptio continua a transcriber wished to keep the two datives לך לעונותיהם separate by inserting the ו. But the form כּוּלּם, Jeremiah 31:34, is equally irregular, except that there the insertion of the ו may be explained in this, or in some similar way.

And I will {g} cleanse them from all their iniquity, by which they have sinned against me; and I will pardon all their iniquities, by which they have sinned, and by which they have transgressed against me.

The repetition is in order that the Jews may consider how great is the grace of God in not merely pardoning (as to the punishment), but also cleansing them (as to the pollution of guilt); not merely one iniquity, but all (Mic 7:18).

33:1-13 Those who expect to receive comforts from God, must call upon him. Promises are given, not to do away, but to quicken and encourage prayer. These promises lead us to the gospel of Christ; and in that God has revealed truth to direct us, and peace to make us easy. All who by sanctifying grace are cleansed from the filth of sin, by pardoning mercy are freed from the guilt. When sinners are thus justified, washed, and sanctified in the name of the Lord Jesus, and by the Holy Spirit, they are enabled to walk before God in peace and purity. Many are led to perceive the real difference between the people of God and the world around them, and to fear the Divine wrath. It is promised that the people who were long in sorrow, shall again be filled with joy. Where the Lord gives righteousness and peace, he will give all needful supplies for temporal wants; and all we have will be comforts, as sanctified by the word and by prayer.
