Enoch, Jubilees, and Jasher
There are several books which have come to us entitled, “Book of Jasher.” One is an ethical treatise from the Middle Ages. It begins with a section on the Mystery of the Creation of the World: It is clearly unrelated to the Biblical Book of Jasher.
Another was published in 1829 supposedly translated by Flaccus Albinus Alcuinus. It opens with the Chapter 1 Verse 1 reading: "While it was the beginning, darkness overspread the face of nature." It is now considered a fake.
The third and most important is by Midrash, first translated into English in 1840. It opens with Chapter 1 Verse 1 reading: "And God said, Let us make man in our image, after our likeness, and God created man in his own image." A comparison of Joshua 10:13 with Jasher 88:63-64 and 2Sam. 1:18 with Jasher 56:9 makes it clear that this Book of Jasher at least follows close enough with the Bible to be the Book of Jasher mentioned in the Bible.
Other books mentioned by name in the Bible are:
