The single Hebrew book Ezra–Nehemiah, with title "Ezra", was translated into Greek around the middle of the 2nd century BC.[3] Slightly later a second, and very different Greek translation was made, in the form of 1 Esdras, from which the deeds of Nehemiah are entirely absent, those sections either being omitted or re-attributed to Ezra instead; and initially early Christians reckoned this later translation as their biblical 'Book of Ezra', as had the 1st century Jewish writer Josephus. 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.
