After doing the thorough exegesis of Ps 33 (a hymn), Ps 34 (a thanksgiving - wisdom poetry), and Ps 35 (a general lament), this study establishes that Pss 33-35 is a Psalm-Triad in the first book of the psalms. The research project shows the purposeful organization of the Psalter and proves that the Psalter is ultimately the Book of Praises.
