I dont know what really psalms are, and I was wondering if you would answer my question. I know that the Books of psalms of the Bible contains psalms, but are the others book of the Wisdom literature psalms as well?
Yep, a few: the Song of Solomon (aka the Song of Songs, not to be confused with WisSol, which isn’t a psalm by genre) is one big Psalm, too. There are psalms scattered all over the OT, and even some (theoretical) fragments of new psalms in the NT.
However, the big group of Psalms has a much stronger and more central liturgical and ritual usage in both Jewish and Christian worship historically. Also, those Psalms are regarded as being more specially prophetic.
Unlike the poetry of the various prophets, which the various psalms often resemble in composition, psalms are meant to be set to music and sung. Different branches of the church have specialized congregations whose sole purpose is to sing the psalms in an unbroken cycle during the year, several times a year, and much of the ancient Catholic and other high church holiday services feature traditional arrangements of the psalms. This is also true of conservative and orthodox Jewish services.
Some of the more important psalms in the NT and OT outside the OT scroll(s) of Psalms, are the songs of Moses and Miriam, and the songs of Zechariah (father of JohnBapt) and of Mary the mother of Jesus (both in GosLuke). Some of Paul’s epistles may be referencing psalms, and GosJohn’s prologue may have been considered a psalm. (I treat it that way in my King of Stories harmonization study.)
