And I will cleanse them from all their iniquity, whereby
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 ) .
