The Testament of Jacob, like the Testaments of Abraham and Isaac, 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, it is considered by some scholars to be a work that was complied in Alexandria around the time that the Testament of Abraham and the Septuagint were translated. The author lists himself as Athanasius, however, nothing else seems to be recorded about him. Several prominent Christian scholars in the early Christian era had the name Athanasius, including Athanasius of Alexandria, who was sainted, however, he lived 500 years too late to be the author of this work.
