What does Psalms Chapter 50 say, and which statements belong to its speaker?

The Latin incipit is Miserere. The separate heading identifies David's repentance and confession and the fourth penitential psalm. The inscription is unto the end, a psalm of David, when Nathan came after he sinned with Bethsabee, with a 2 Kings 12 reference. The admitted span does not itself name Urias or narrate murder. David asks mercy in great and tender mercies, blotting iniquity, further washing and cleansing. He knows his sin, always before him, says he sinned only to God and did evil before Him so His words be justified and He overcome when judged.

He says he was conceived in iniquities and sins, that God loved truth and made uncertain and hidden wisdom manifest. Future hyssop sprinkling, washing whiter than snow and joy to hearing accompany humbled bones' rejoicing. He asks an averted face from sins and blotting of all iniquities, a created clean heart and renewed right spirit within bowels, no expulsion or removal of God's holy spirit. Restoration of salvation's joy and strengthening with a perfect spirit are requested, not completed outcomes.

He will teach unjust people God's ways and wicked people shall convert. He asks delivery from blood, with future extolling of justice, opening of lips and praise. If God had desired sacrifice he would have given it, but burnt offerings will not delight Him. An afflicted spirit is sacrifice and a contrite humbled heart will not be despised. He seeks favor for Sion and built Jerusalem walls; then sacrifice of justice, oblations and whole burnt offerings shall be accepted and calves laid on the altar. The closing future sacrifices remain part of the prayer rather than an assertion that only inward sacrifice is ever acceptable.
