This dissertation seeks to refine the meaning of [Torah] in Psalms 1, 19, 37, 40, 78, 89, 94, 105, and 119.

Chapter 1 introduces the research question, thesis, and surveys the various approaches to the meaning of [Torah] in book of Psalms. Chapter 2 evaluates current linguistic methods that have been applied to the semantic study of Hebrew words. This chapter also explains the exegetical approach of the dissertation. Chapter 3 surveys the meaning of [Torah] in the Old Testament. The purpose of this chapter is to study the diverse manner in which the term is employed throughout the Old Testament. The procedure of establishing a definition will produce the parameters within which [Torah] can be understood in the book of Psalms. Chapter 4 surveys the semantic usage of [Torah] in Psalms 1, 19, 37, 40, 78, 89, 94, 105, and 119. The exegetical analysis will include an evaluation of words, phrases, and themes that might indicate the semantic usage of [Torah] in context.
