Overview
Psalm 51, one of the penitential psalms, is the 51st psalm of the Book of Psalms, beginning in English in the King James Version: "Have mercy upon me, O God". In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 50. In Latin, it is known as Miserere, in ), especially in musical settings. The introduction in the text says that it was composed by David as a confession to God after he sinned with Bathsheba.
The psalm forms a regular part of Jewish, Catholic, Eastern Orthodox and Protestant liturgies.
Background and themes
Psalm 51 is based on the incident recorded in 2 Samuel, chapters 11–12. David's confession is regarded as a model for repentance in both Judaism and Christianity.
The Midrash Tehillim states that one who acknowledges that he has sinned and is fearful and prays to God about it, as David did, will be forgiven. But one who tries to ignore his sin will be punished by God. The Talmud (Yoma 86b) cites verse 5 in the Hebrew (verse 3 in English versions), "My sin is always before me", as a reminder to the penitent to maintain continual vigilance in the area in which he transgressed, even after he has confessed and been absolved.
