Song of Ascents is a title given to fifteen of the Psalms, 120–134, each starting with the superscription "Shir Hama'aloth", or, in the case of Psalm 121, Shir Lama'aloth. They are also variously called Gradual Psalms, Fifteen Psalms, Songs of Degrees, Songs of Steps, songs for going up to worship or Pilgrim Songs.

Psalm 121 is the 121st psalm of the Book of Psalms, beginning in English in the King James Version: "I will lift up mine eyes unto the hills, from whence cometh my help”. In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 120. In Latin, it is known as Levavi oculos meos in montes.
