All nations shall serve him; that is, all these nations; and some think that it is expressed in the article used here demonstratively, though not so taken notice of by our translators. And his son, and his son's son; and Evil-merodach his son, who succeeded him, Jeremiah 52:31, and Belshazzar his grandchild, Daniel 4:1,11. Until the period of his kingdom shall come, (for nations have their periods,) which was after seventy years, according to Jeremiah 29:10, during which years some say four princes ruled in Babylon, the Scripture mentions but three. After that he shall himself be conquered, as it came to pass in Belshazzar's time, Daniel 5:30, Darius the emperor of the Medes taking his kingdom.
