1st Testament of Abraham

The 2nd version has also been considered scripture by several Churches and Israelite groups, including the Coptic Church in Egypt, Beta Israel in Ethiopia, and Beta Abraham in Sudan. The Testament of Abraham was also quoted by Origen circa 200 AD, and later in the Qur'an, showing it's significance to the people of the Middle East in the early Christian era. It is generally accepted that Origen was quoting the 1st version, meaning the text had already been Christianized by his time, however, the final paragraph is believed to be a later addition by an Orthodox cleric some time after the Council of Nicene in the 4th-century.
