Psalm 51:2-5BSB
Wash me clean of my iniquity and cleanse me from my sin. For I know my transgressions, and my sin is always before me. Against You, You only, have I sinned and done what is evil in Your sight, so that You may be proved right when You speak and blameless when You judge. Surely I was brought forth in iniquity; I was sinful when my mother conceived me.

But if they will confess their iniquity and that of their fathers in the unfaithfulness that they practiced against Me, by which they have also walked in hostility toward Me— and I acted with hostility toward them and brought them into the land of their enemies—and if their uncircumcised hearts will be humbled and they will make amends for their iniquity, then I will remember My covenant with Jacob and My covenant with Isaac and My covenant with Abraham, and I will remember the land.
John synthesizes Levitical purification language with prophetic new covenant promises. Psalm 32 and 51 model confession-forgiveness pattern grounded in sacrificial atonement. David's plea "Wash me clean... and cleanse me" assumes the Levitical system's blood purification. Ezekiel and Jeremiah prophesy eschatological cleansing exceeding ritual washings - internal heart transformation. John's "faithful and just" recalls covenant formulae (Deuteronomy 7:9) - God's faithfulness to forgive flows from His justice satisfied through Christ's propitiatory death (1 John 2:2). The hermeneutical move: what Levitical sacrifices typified and what prophets promised, Christ accomplished. Confession now accesses the efficacy of His once-for-all cleansing. Christians live under perpetual atonement - not needing repeated sacrifices but confessing to appropriate Christ's finished work. This sustains assurance: sin confessed is sin forgiven because the Just One bore our justice.
