Sefer HaYashar (midrash)
The Sefer haYashar (first edition 1552) is a Hebrew midrash also known as the Toledot Adam and Dibre ha-Yamim be-'Aruk. The Hebrew title may be translated Sefer haYashar "Book of the Upright Man," but it is known in English translation mostly as The Book of Jasher following English tradition. The book is named after the Book of Jasher mentioned in Joshua and 2 Samuel.
This is among several texts purporting to be the original "Book of Jasher." The text is not accepted as such in rabbinical Judaism.
