Psalm 122

Psalm 122 is the 122nd psalm of the Book of Psalms, beginning in English in the King James Version: "I was glad" and in Latin entitled Laetatus sum. It is attributed to King David and one of the fifteen psalms described as A song of ascents (Shir Hama'alot). Its title, I was glad, is reflected in a number of choral introits by various composers. In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 121.
