Psalms 51:2

Psalms 51:2. Wash me thoroughly from mine iniquity, and cleanse me from my sin.

Nothing about the punishment observe - he does not mention that. The true penitent, though he dreads punishment, much more dreads sin. It is sinfulness - sin that he would be delivered from. "Wash me." Thou must do it; no other washing will suffice. Wash me thoroughly, till I am perfectly cleansed: cleanse me from my sin - my sin. I do not lay it on anyone else; cleanse me from it.
