Once more:
''First, stories about Daniel had circulated before the time of Antiochus and had long been used to encourage faithful obedience to and observance of Jewish law. However,
all the stories of the book of Daniel relate
directly to the persecution under Antiochus: loyalty to the Jewish food laws and the refusal to worship images of other gods had become a question of life and death in Antiochus' crisis-ridden empire.
Second, the name Nebuchadnezzar contains a disguised reference to Antiochus to those acquainted with Hebrew numbering. The Babylonian king of 605 - 562 BCE was in fact called
nabu-kuddurri-usur which should be transliterated into Hebrew script as Neuchad
Rezzar (as it is in eg.
Jeremiah 46:2,
39:11). The change of that one letter gives this name the same numerical value in Hebrew (which had no separate numbers and so used letters to represent numbers) as the name Antiochus Epiphanes. This is too coincidental to be accidental and too contrived to be miraculous.
Thirdly, the whole genre of Apocalyptic literature which Daniel represents only developed during the period of crisis and persecution under Antiochus. The few examples of Apocalyptic in the Old Testament are all late, and the popularity of Apocalyptic in the New Testament is indication that it was a relatively new and popular literary form around the time of Jesus.''
