The book "BC 4000: A Historical Study of the Old Testament"connects each book of the Old Testament according to the flow of history, organizing them in a way that makes the Bible easier to understand. It is a comprehensive work that encompasses the earliest period of human history as well as the history of the Jewish people. This book is not intended to teach doctrine. It focuses solely on historical facts and deals only with factual historical content. Regardless of religious affiliation-whether Christian, Muslim, Catholic, or any other denomination-anyone who wishes to read and understand the Bible can study its history in a pure and objective manner through this book. Malachi, the last prophet of the Old Testament, lived around 430 BC. Although the history of the Jewish people continued after that time, the Old Testament contains no records beyond Malachi. Therefore, through research and organization based on other historical sources, this book continues and connects the history of the Jewish people up to the period of the New Testament. Furthermore, it includes an account of the miraculous establishment of the State of Israel in the 20th century, enabling readers to understand the modern history of the Jewish people. Those who recognize the value of the Bible will feel a strong desire to own this book after reading it.
