Psalm 151

Psalm 151 is the name given colloquially to a short psalm which is found in most copies of the Septuagint (Greek language translation of the Bible) but not in the Hebrew text. It was found at Qumran: 11QPs(a)151. However, the title given to this psalm in the Septuagint ("This Psalm is ascribed to David and is outside the number. When he slew Goliath in single combat." ) indicates that it is supernumerary, and no number is affixed to it. Most Biblical scholars consider it to be an addition by the compilers and translators of the Septuagint.

The title of the psalm indicates that it was written by King David after his battle with Goliath. The text expresses how David was the least of his brothers, and yet God chose him to be anointed king. It goes on to commemorate how David killed Goliath with the Philistine's own sword.

The Eastern Orthodox Church accepts Psalm 151 as canonical. Roman Catholics, Protestants and most Jews consider it apocryphal. However, it is found in an appendix in some Catholic Bibles, such as certain editions of the Latin Vulgate, as well as in some ecumenical translations, such as the NRSV.
