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." [1]) 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.
