Song of Ascents is a title given to fifteen of the Psalms, 120–134 (119–133 in the Septuagint), that each starts with the ascription (Hebrew: שיר המעלות, Shir Hama'aloth‎). They are also variously called Gradual Psalms, Songs of Degrees, Songs of Steps or Pilgrim Songs. The probable origin of this name is the circumstance that these psalms came to be sung by the people on the ascents or goings up to Jerusalem to attend the three pilgrim festivals (Deuteronomy 16:16) or by the kohanim (priests) as they ascended the steps to minister at the Temple in Jerusalem.
