Christ Teaching Us How To Repent In The Psalms

Just as when Christ instructed his disciples on how to pray he mouthed words of repentance for them to say: "Forgive us our trespasses...;" so in the Psalms he gives his people and his church the words of repentance  to say: "Wash me thoroughly from my iniquity..." (Psalm 51:2; and so many other places). Christ is in the Psalms in many ways, including, as High Priest, teaching his church the words and ways of repentance and faith in God.
