A good deal of biblical scholarship on the book of Daniel assumes that Daniel 7–12 was written after 165 B.C. This date is very difficult to reconcile with the actual historical evidence. For instance, the book of Daniel was embraced by all sects of Judaism, whereas other literature produced after the schisms took place was only embraced by particular groups within Judaism.
As noted in an earlier post, the covenanters at Qumran appear to have gone to the shores of the Dead Sea soon after 200 B.C., and there are at least 8 manuscripts of Daniel at Qumran. Is it plausible that a book produced at that time would be accepted by all groups within Judaism, so that even those who separated themselves from the corrupt temple and retreated to Qumran would take this newly produced book with them to the desert? Amid such fierce controversies, would such a book also have been held sacred back in Jerusalem?
The point of this post is to highlight another piece of historical evidence from the Jewish Antiquities by Josephus. Flavius Josephus describes an event that he presents as having taken place in 332 BC (for the date, cf. the Loeb Classical Library ed. of Ant. XI 317, p. 467 notes c and e):
“. . . he [Alexander the Great] gave his hand to the high priest and, with the Jews running beside him, entered the city. Then he went up to the temple, where he sacrificed to God under the direction of the high priest, and showed due honour to the priests and to the high priest himself. And, when the book of Daniel was shown to him, in which he had declared that one of the Greeks would destroy the empire of the Persians, he believed himself to be the one indicated; and in his joy he dismissed the multitude for the time being, but on the following day he summoned them again and told them to ask for any gifts which they might desire. . .”
Two things to note here: first, Josephus clearly regarded Daniel to be the author of the book of Daniel, “the book of Daniel . . ., in which he had declared . . .” Second, Josephus placed this event in 332 BC, so Josephus believed that the book of Daniel had been written by then.
