With three synonyms (“transgressions,” “iniquity,” and “sin”), David confesses the totality of his sin. He no longer hides what could never be hidden. Great is David’s sin but not greater than the forgiveness of the self-revealed One, who is “merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness” (Ex. 34:6). David does not offer to work for a wage but to be given grace, knowing that his sin is before him (and everyone else who has ever read this psalm). His prayer is not that his sin be blotted out of human history, but that by God’s grace it would be forgiven. And so it was. Such is the merciful forgiveness of God.
