This book is a commentary on Daniel 9 in the Hebrew-language based Jewish Scriptures. The first part of the book is focussed on verse 25. I provide detailed definitions of key Hebrew words, but also discuss verse structure and Hebrew cantillation marks, both of which designate two distinct, independent parts. For a long time I had subscribed to the idea that this verse referred to the coming of the person known as The Messiah. In my youth, at the request of my atheist mother, I had read the book 'The Late Great Planet Earth, ' by Hal Lindsey, which introduced many to the idea of the Messiah and a Christian premillennial end-times view. Last summer (2024) I felt driven to better understand Daniel 9. I decided to look at the Hebrew more thoroughly, wanting to know the purpose of cantillation marks having to do with grammar. To my surprise, I learned that an Ethnacta Emperor accent, which separates longer verses into two distinct sections, occurs in the "seven weeks" of Daniel 9:25: "Know therefore and discern, that from the going forth of the word to return to and to build Yerushalam unto Mashiach nagid shall be seven weeks; and for sixty-two weeks, it shall be built again, with broad place and moat, but in troublous times." Thus, contrary to the teaching of Christian premillennialists where they teach that Messiah comes after the end of the sixty-two weeks, at the Ethnacta cantillation mark the Messiah (Mashiach Nagid) is found at the point in time of the seven weeks (49 years) at the beginning of the timeline from the order to return to and build Yerushalam! This, as well as other supporting information is well documented in this book, "Ad Mashiach Nagid: The Messiah In Daniel 9." I have a chapter on The Ten Commandments from the Leningrad Codex, and also include basic information for the study of the ancient Hebrew language in my chapter "Seek Yehovah."
