This is an Old Testament paper on the relevance of Hittitology to the understanding of the Pentateuch:
In the last 100 years Hittitology has moved from virtual non-existence to a significant field of study. This paper seeks to explore some of the findings of Hittitology, and evaluate their relevance to the understanding of the Pentateuch. The paper follows this outline: Introduction, Biblical References to Hittites, Extra-Biblical Historical Survey (Hittite History, Neo-Hittites History, Pre-Hittite History, Hittite Treaties), The Chronology Problem, Pentateuchal Significance (Who were the the Biblical Hittites, Hittite Treaties and Biblical Covenant), Conclusions. A cautious approach to the use of historical and archaeological studies is taken, while still recognising the valuable contributions they make to Pentateuch studies.
(I actually found this paper very hard to write, but the research was very helpful and an eye-opener for me regarding the value and level of confidence we can have in historical and archeological studies...)
