The Testament of Judah, like the other Testaments of the Twelve Patriarchs, is considered to be a Jewish work that was added to by Christians in the Christian era. It is unclear when it comes from, however, fragments of the Testaments of Judah and and Naphtali have been found among the Dead Sea Scrolls in Hebrew, dating to between 37 BC and 44 AD. Given the number of references to primordial gods, it is unlikely to be the work of a Pharisee, and was likely translated into Hebrew from Aramaic or Greek. As it has some of the same anti-Levitical content as the Testament of Levi, it was likely a text written by the Tobian Jews mentioned in 2nd Maccabees, that lived in Seleucid controlled regions.
