The Book of Jasher, a lost book of the Bible comprising ninety-one chapters, is presented here complete in the celebrated 1840 English translation by Moses Samuel. Referenced twice in the New Testament scripture - once in Joshua and once in Second Samuel - the Book of Jasher is also known as the Sefer haYashar or the Book of the Upright. Its contents are wide-ranging; the creation of Man and the story of Adam and Eve, and the descendants of Noah comprise part of the text. The testing of Abraham by God also features, while Abraham's dialogue is notably expanded far beyond what is said in the Hebrew Bible. The text has gained a great following since its translation to English in the mid-19th century. The Church of Latter-Day Saints founder Joseph Smith praised its detail, noting the book's elaboration on the condition of the Earth following the Great Flood.

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" - 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. Although it is presented as the original "Book of Jasher" in the translations such as that of Moses Samuel (1840), it is not accepted as such in rabbinical Judaism, nor does the original Hebrew text make such a claim. It should not be confused with the very different Book of Jasher (Pseudo-Jasher) printed by Jacob Ilive in 1751, which claimed to have been translated by the English monk Alcuin.

The Book of Jasher covers the Mosaic period of the Bible presented in Genesis, Exodus, Numbers, Deuteronomy, and Joshua in greater detail and with explanations not found in the present Old Testament Documents. This apocryphal book of the Bible has been considered by some to be the original beginning to the Bible and is referenced in both the Book of Joshua and the Second Book of Samuel. Is not this written in the Book of Jasher?-Joshua, X. 13. Behold it is written in the Book of Jasher.-II. Samuel, I. 18

This copy of The Book of Jasher was published in 1840 and was translated from the original Hebrew into English by Mordecai M. Noah and Alexander S. Gould.
