So this Daniel prospered in the reign of Darius
This Daniel, of whom so much has been said all the preceding chapters, and who had been so lately and so wonderfully delivered from the lions' den, the same flourished throughout the reign of Darius the Mede; continued a favourite with the king; retained his honour and dignity; and kept his posts and places of trust and profit. Darius the Mede reigned two years; though Jarchi says he reigned but one, and was slain in war; for which he refers to Joseph ben Gorion, who has not a word of it. And in the reign of Cyrus the Persian;
who, as Jacchiades says, was the son-in-law of Darius, and inherited the kingdom after him; which is true, for he married the daughter of Cyaxares or Darius who was his uncle, and succeeded him as sole monarch of the empire: he reigned with him the two years he had the government of the Babylonish monarchy; and when he died, it solely devolved on him, who reigned seven years after, as Xenophon F19 relates; but the canon of Ptolemy ascribes nine years to his reign, which includes the two years he was partner with Darius. Daniel was in the same favour with this prince as the former, who in the first year of his reign proclaimed liberty to the Jews to return to their country, and build their temple; whether Daniel lived throughout his reign is not certain; he was alive in the third year of it, as appears from ( Daniel 10:1 ) , some take Darius and Cyrus to be one and the same person, and render this last clause as explanative of the former, "even", or, "that is, in the reign of Cyrus the Persian" F20.
