And in the second year of the reign of Nebuchadnezzar
It was in the first year of Nebuchadnezzar's reign that Daniel was carried captive, ( Jeremiah 25:1 ) , three years Daniel had been under tutors; at the end of which he was presented to the king, as is related in the preceding chapter; and yet the following dream was in the second of his reign: this creates a difficulty, which is solved by some thus: in the second year after the destruction of the temple, so the Jewish chronicle F15, with which Jarchi agrees; others, as Aben Ezra, in the second year of his monarchy, after he had subdued all the nations round about; and so Josephus says F16, it was in the second year after the destruction of the Egyptians. R. Moses the priest, in Aben Ezra, would have it to be the second year to his reign, to the end of it, when there were only two years wanting to it; a very unusual way of reckoning indeed! and therefore justly rejected by Aben Ezra: but all these dates are too late, since Daniel long before these times was well known, and in great fame for his wisdom; whereas, at this time, it does not appear that he was much known, or in great request: it is better either to render it, "in the second year", that is, after Daniel and his companions had been presented to the king, and promoted; even in the reign of Nebuchadnezzar,
as opposed to the reign of Darius or Cyrus, in which he flourished also: or rather this was the second year of Nebuchadnezzar's reigning alone; for he had been taken into partnership in the throne with his father before his death, as Berosus
