There may be no more impassioned or beautiful prayer for forgiveness and renewal in the Bible than here. The poet's wrongdoing has overwhelmed him. His remorse and his plea are intense. David accepts personal responsibility for what he's done, Psa 51:1-9. Four different words for sin: transgressions (Psalms 51:1,3); iniquity (Psa 51:2,5,9); evil (Psa 51:4); sin (Psa 51:2-5,9). David's multiple petitions for forgiveness (Psa 51:1,2,7,9,14). David's prayer for renewal, Psa 51:10-13. David's vow to offer spiritual sacrifices, Psa 51:14-17. David's intercession for Jerusalem, Psa 51:17-18.
