in the Psalms Scroll of the Dead Sea Scrolls. Some versions of the Peshitta (the Bible used in Syriac churches mainly in the Middle East) include Psalms 152–155. There are also the Psalms of Solomon, which are a further 18 psalms of Jewish origin, likely originally written in Hebrew, but surviving only in Greek and Syriac translation. These and other indications suggest that the current Western Christian and Jewish collection of 150 psalms were selected from a wider set. Primary types Hermann Gunkel's pioneering form-critical work on the psalms sought to provide a new and meaningful context in which to interpret individual psalms—not by looking at their literary context within the Psalter (which he did not see as significant), but by bringing together psalms of the same genre () from throughout the Psalter. Gunkel divided the psalms into five primary types: Hymns Hymns are songs of praise for God's work in creation or history. They typically open with a call to praise, describe the motivation for praise, and conclude with a repetition of the call. Two sub-categories are "enthronement psalms", celebrating the enthronement of Yahweh as king, and Zion psalms, glorifying Mount Zion, God's dwelling-place in Jerusalem. Gunkel also described a special subset of "eschatological hymns" which includes themes of future restoration (Psalm 126) or of judgment (Psalm 82). Communal laments Communal laments are psalms in which the nation laments some communal disaster. Both communal and individual laments typically but not always include the following elements: address to God, description of suffering, cursing of the party responsible for suffering, protestation of innocence or admission of guilt, petition for divine assistance, faith in God's receipt of prayer, anticipation of divine response, and a song of thanksgiving. In general, the individual and communal subtypes can be distinguished by the use of the singular "I" or the plural "we". However, the "I" could also be characterising an individual's personal experience that was reflective of the entire community. Royal psalms Royal psalms deal with such matters as the king's coronation, marriage and battles. None of them mentions any specific king by name, and their origin and use remain obscure; several psalms, especially Psalms 93–99, concern the kingship of God, and might relate to an annual ceremony in which Yahweh would be ritually reinstated as king. Individual laments Individual laments are psalms lamenting the fate of the psalmist. By far the most common type of
