The Book of Jasher follows the biblical accounts in Genesis, Exodus, Numbers, Deuteronomy, and Joshua. It reads like the Bible but includes interpolations and elaborations not found in the Bible. In addition, it sheds light on Bible stories from the time of Adam and Eve, the ministry of Enoch, and the account of the great Deluge during the days of Noah to the Tower of Babel, nefarious Nimrod, and faithful Abraham and his descendants.
As Moredecai M. Noah wrote in his introduction to the 1840 English translation: "Without giving it to the world as a work of Divine inspiration, or assuming the responsibility to say that it is not an inspired book, I have no hesitation in pronouncing it a work of great antiquity and interest, and a work that is entitled, even regarding it as a literary curiosity, to a great circulation among those who take pleasure in studying the scriptures."
