The Testament of Abraham was likely written originally in Greek, by someone living in Egypt at the time. This is due to the fact that the vocabulary found in the text is quite similar to the vocabulary used in the later books of the Septuagint, which were being written at that time, in addition to other books, such as 3 Maccabees, that we know were written around that time in Egypt. In addition, there are aspects of the story that seem to reflect aspects of Egyptian life, such as the three judgments which mirror the three levels of Egyptian government.
