From the third century the Christian Old Testament in Greek supplemented the text of 1 Esdras with the older translation of Ezra-Nehemiah, naming the two books Esdras A and Esdras B respectively; and this usage is noted by the 3rd century Christian scholar Origen, who remarked that the Hebrew 'book of Ezra' might then be considered a 'double' book. Jerome, writing in the early 5th century, noted that this duplication had since been adopted by Greek and Latin Christians.
