The Testaments of the Twelve Patriarchs is a constituent of the apocryphal scriptures connected with the Bible. It is a pseudepigraphical work comprising the dying commands of the twelve sons of Jacob. It is part of the Oskan Armenian Orthodox Bible of 1666. Fragments of similar writings were found at Qumran, but opinions are divided as to whether these are the same texts. It is considered apocalyptic literature.
The Testaments were written in Hebrew or Greek, and reached their final form in the 2nd century CE. In the 13th century they were introduced into the West through the agency of Robert Grosseteste, Bishop of Lincoln, whose Latin translation of the work immediately became popular. He believed that it was a genuine work of the twelve sons of Jacob, and that the Christian interpolations were a genuine product of Jewish prophecy; he accused Jews of concealing the Testaments "on account of the prophecies of the Saviour contained in them."
With the critical methods of the 16th century, Grosseteste's view of the Testaments was rejected, and the book was disparaged as a mere Christian forgery for nearly four centuries. Presently, scholarly opinions are still divided as to whether it is an originally Jewish document that has been retouched by Christians, or a Christian document written originally in Greek but based on some earlier Semitic-language material. Scholarship tends to focus on this book as a Christian work, whether or not it has a Jewish predecessor (Vorlage).
Testaments are regarded as exhortatory writings; ethics therefore are fundamental to the text. The Testaments have many different ethical motifs, the foremost of which is adhering to God's commandments. In this regard, it is interesting to note that the ethics in the Testaments generally start out very precise; each testament discusses a certain vice or virtue. Usually this is then concluded with a very vague and general reference to God's law and commandments.
Another theme that has been extensively discussed by Hollander is the role that Joseph plays in the ethics. He is often the example of an ethical man, and the deeds of the patriarchs are often weighed against those of Joseph.
As argued by Robert Henry Charles, who studied and translated the Testaments in the beginning of the 20th century,
