Isaiah 39:1
1At that time, Merodach-baladan the son of Baladan, king of Babylon, sent letters and a present to Hezekiah, for he heard that he had been sick, and had recovered.
Wesley: The king of Babylon sends ambassadors with letters and a present to Hezekiah, who shews them his treasures, v. 1, 2. Berodach-baladan—He seems to have been the king of Assyria’s vice-roy in Babylon, and upon that terrible slaughter in the Assyrian host, and the death of Sennacherib, and the differences among his sons, to have usurped absolute sovereignty over Babylon. And either himself or his son destroyed the Assyrian monarchy, and translated the empire to Babylon. Sent—Partly, for the reasons mentioned, 2 Chron. 32:31, and partly, to assure himself of the assistance of Hezekiah against the Assyrians, their common enemy.
Merodach-baladan’s envoys come with congratulations and gifts, but Wesley notes a political motive: an ally against Assyria. The friendly visit is a test Hezekiah does not recognize.
Calvin: at that time. Some think that this was the first king of the Chaldee nation; for his father, Baladin, had held the government over the Babylonians without the title of king. This Merodach, therefore, after having reigned twelve years, subdued the Assyrians, and made them tributaries to the Chaldeans; for it is a mistake to suppose that the war was begun by Nebuchadnezzar. Sent letters and a present to Hezekiah: this was done craftily by the Babylonian, in order to flatter and cajole Hezekiah; the pretence was, to congratulate Hezekiah on having recovered from his disease; yet sacred history appears to assign another reason, which was, that Merodach was induced by a miracle.
Key contrast Both keep Merodach-baladan as that king of Babylon who sent the embassy. Wesley reads him as the king of Assyria’s vice-roy in Babylon who, after the slaughter in the Assyrian host and the death of Sennacherib, usurped absolute sovereignty over Babylon; either himself or his son destroyed the Assyrian monarchy and translated the empire to Babylon. Calvin takes him as the first king of the Chaldee nation: his father Baladin had held the government without the title of king; this Merodach, after having reigned twelve years, subdued the Assyrians and made them tributaries to the Chaldeans; it is a mistake to suppose that the war was begun by Nebuchadnezzar.
