30. HERODOTUS and XENOPHON confirm Daniel as to the suddenness of the event. Cyrus diverted the Euphrates into a new channel and, guided by two deserters, marched by the dry bed into the city, while the Babylonians were carousing at an annual feast to the gods. See also Isa 21:5; 44:27; Jer 50:38, 39; 51:36. As to Belshazzar's being slain, compare Isa 14:18-20; 21:2-9; Jer 50:29-35; 51:57.

     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].
