      Isa 39:1-8. HEZEKIAH'S ERROR IN THE DISPLAY OF HIS RICHES TO THE BABYLONIAN AMBASSADOR.

      1. Merodach-baladan--For a hundred fifty years before the overthrow of Nineveh by Cyaxares the Mede, a succession of rulers, mostly viceroys of Assyria, ruled Babylon, from the time of Nabonassar, 747 B.C. That date is called "the Era of Nabonassar." Pul or Phallukha was then expelled, and a new dynasty set up at Nineveh, under Tiglath-pileser. Semiramis, Pul's wife, then retired to Babylon, with Nabonassar, her son, whose advent to the throne of Babylon, after the overthrow of the old line at Nineveh, marked a new era. Sometimes the viceroys of Babylon made themselves, for a time, independent of Assyria; thus Merodach-baladan at this time did so, encouraged by the Assyrian disaster in the Jewish campaign. He had done so before, and was defeated in the first year of Sennacherib's reign, as is recorded in cuneiform characters in that monarchs palace of Koyunjik. Nabopolassar was the first who established, permanently, his independence; his son, Nebuchadnezzar, raised Babylon to the position which Nineveh once occupied; but from the want of stone near the Lower Euphrates, the buildings of Babylon, formed of sun-dried brick, have not stood the wear of ages as Nineveh has.
      Merodach--an idol, the same as the god of war and planet Mars (Jer 50:2). Often kings took their names from their gods, as if peculiarly under their tutelage. So Belshazzar from Bel.
      Baladan--means "Bel is his lord." The chronicle of EUSEBIUS contains a fragment of BEROSUS, stating that Acises, an Assyrian viceroy, usurped the supreme command at Babylon. Merodach- (or Berodach-) baladan murdered him and succeeded to the throne. Sennacherib conquered Merodach-baladan and left Esar-haddon, his son, as governor of Babylon. Merodach-baladan would naturally court the alliance of Hezekiah, who, like himself, had thrown off the yoke of the Assyrian king, and who would be equally glad of the Babylonian alliance against Assyria; hence arose the excessive attention which he paid to the usurper.
      sick--An additional reason is given (2Ch 32:31). "The princes of Babylon sent to enquire of the wonder that was done in the land"; namely, the recession of the shadow on Ahaz' sundial; to the Chaldean astronomers, such a fact would be especially interesting, the dial having been invented at Babylon.
