The book of Jasher, or the book of the Just, is a book of historical Hebrew origin that is mentioned several times in the Old Testament, and in the same way as the first canonical books, it tells us in an expanded and detailed way the creation of man, his relationships, the life of the prophets, the patriarchs, Moses, and many events of collective and religious interest.

“The Lord, in whom I trust, said to me: Abraham, you will lack nothing, because I will bless you in all the works of your hands because you have been faithful and upright in all my ways, and you have never reneged on any command that I have given you”. Book of Jasher
