Psalm 55

Psalm 55 is the 55th psalm of the Book of Psalms, beginning in English in the King James Version, "Give ear to my prayer, O God, and hide not thyself from my supplication". The Book of Psalms forms part of the ketuvim, the third section of the Hebrew Bible, and is part of the Christian Old Testament. In the slightly different numbering system of the Greek Septuagint version of the Bible, and in the Latin Vulgate, this psalm is Psalm 54. In Latin, it is known as "Exaudi Deus orationem meam". The psalm is a lament in which the author grieves because he is surrounded by enemies, and one of his closest friends has betrayed him. The psalm forms a regular part of Jewish, Catholic, Lutheran, Anglican and other Protestant liturgies. Metrical hymns in English and German were derived from the psalm, and it has been set to music.
