4The 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."
