Psalms 51:4

Against Thee, Thee only, have I sinned and done this evil in Thy sight, for every transgression of the Law, whether it be directed against the First or against the Second Table, is an infraction of the will of God and an insult to His dignity and holiness; for we are responsible to God alone, also in our conduct toward our neighbor, our apology to the neighbor for a wrong committed being a fruit of our repentance over against God; that Thou mightest be justified when Thou speakest, and be clear when Thou judgest, for every sin that is revealed and punished will in the end serve to set forth the holiness and justice of God, to glorify Him in the perfection of His essence.
