David Rosenberg suggests in his The Book of David that it was written in 1100 BC or thereabouts. Theologian Joseph Barber Lightfoot suggested that it was merely another title for the mysterious biblical Book of Jasher.
The Book of the Wars of the Lord is cited in the medieval Book of Jasher as being a collaborative record written by Moses, Joshua, and the children of Israel.
A notable reference to an unnamed book is mentioned in, where God commanded Moses to inscribe an Israelite military victory over the Amalekites in the book and recount it later in the hearing of his successor Joshua. The book is not specifically mentioned by name. However, some Torah scholars such as Moses ibn Ezra have suggested this book may refer to the Book of the Wars of the Lord.
