This is a faithful translation from the original Hebrew into English. Sefer Ha-Yashar, cited in Joshua 10:13, was thought lost for a long time. It should have been included among the other books of the Bible but it was omitted as were many other books

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.
