This book is an expansion of lectures to my students at the Catholic University of Eastern Africa and Maseno State University in Kenya.It is my hope that the book will meet the needs of undergraduates, postgraduates, researchers of Religion and teachers of Old Testament Studies, The Pentateuch, catechesis and evangelization, and Theology of the old Testament in both church and secular institutions. It is a book that can be used as a class text for students taking Religion or Scripture. It is easy to read and can cover three credit hours for a core course in a university programme of studies. It evidently shows that the God of Abraham and Isaac is the same God we worship today. It can be used also as an hand book for all students taking Religion. It is a book that can be used by all Christians regardless of denomination.
