31. Darius the Median--that is, Cyaxares II, the son and successor of Astyages, 569-536 B.C. Though Koresh, or Cyrus, was leader of the assault, yet all was done in the name of Darius; therefore, he alone is mentioned here; but Da 6:28 shows Daniel was not ignorant of Cyrus' share in the capture of Babylon. Isa 13:17; 21:2, confirm Daniel in making the Medes the leading nation in destroying Babylon. So also Jer 51:11, 28. HERODOTUS, on the other hand, omits mentioning Darius, as that king, being weak and sensual, gave up all the authority to his energetic nephew, Cyrus [XENOPHON, Cyropædia, 1.5; 8.7].
      threescore and two years old--This agrees with XENOPHON [Cyropædia, 8.5,19], as to Cyaxares II.
