Psalm 51, one of the penitential psalms,^[1] 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,^[2] (Ancient Greek: ἐλέησόν με ὁ θεός, romanized: eléēsón me ho Theós) in Ancient Greek:  Ἥ Ἐλεήμων, romanized: Hḗ Eleḗmōn), 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.
