sn In vv. 1b–2 the psalmist uses three different words to emphasize the multifaceted character and degree of his sin. Whatever one wants to call it (“rebellious acts,” “wrongdoing,” “sin”), he has done it and stands morally polluted in God’s sight. The same three words appear in Exod 34:7, which emphasizes that God is willing to forgive sin in all of its many dimensions. In v. 2 the psalmist compares forgiveness and restoration to physical cleansing. Perhaps he likens spiritual cleansing to the purification rites of priestly law.
