39:1 The phrase "At that time"(cf. 38:1) anticipates a specially significant event and ties it to what preceded in chapter 38. As this verse explains, the events that follow happened after Hezekiah had recovered from his illness (38:5). This was most likely during the year 701 B.C. before Sennacherib's invasion of Jerusalem (chs. 36-37; cf. 2 Kings 18:16).
Merodach-baladan (Cuneiform "Marduk-apal-iddina,"lit. the god Marduk has given a son) raised Babylon to a position from which it threatened and eventually overthrew Assyrian dominance in the ancient Near East (cf. 21:1-10). He was the first king of Babylon, and he led that nation during two periods: 721-710 B.C. and 703-702 B.C.378In 710 B.C. Sargon, another Babylonian leader, ousted him, but in 702 B.C. the Assyrians defeated him. After this defeat, he continued to foment revolt against Assyria in the Fertile Crescent. This seems to have been his motivation for cultivating Hezekiah's friendship by sending letters and a present when he heard of Hezekiah's recovery.
39:2 Hezekiah received Merodach-baladan warmly since he had expressed sympathy toward him and because the Babylonians shared Judah's antagonism toward Assyria. But showing the Babylonians all of his wealth and military resources went beyond what Hezekiah needed to do for such a friendly visitor.379It expressed a desire to share these resources with an ally who might help Judah oppose Assyria. Thus Hezekiah's act demonstrated trust in Babylon and reliance on her for safety.
"Here was a ready-made opportunity for Hezekiah to glorify God before the pagan Babylonians, to tell of his greatness and of his grace. Instead, he succumbed to the temptation to glorify himself and to prove to the Chaldeans that he was a worthy partner for any sort of coalition they might have in mind. There is no indication that they were interested in such an alliance, however. Much more likely they simply wished to encourage someone whom they viewed as a petty kinglet without making any commitment on their part."380
This visit constituted a divine test of Hezekiah's heart. Second Chronicles 32:31 reads, "And even in the matter of the envoys of the rulers of Babylon, who sent to him to inquire of the wonder that had happened in the land [namely, Hezekiah's recovery], God left him alone only to test him, that He might know all that was in his heart."
39:3-4 God's Spirit and Hezekiah's failure to trust the Lord undoubtedly moved Isaiah to confront Hezekiah. First, the prophet asked about the visit of the Babylonian ambassadors and what Hezekiah had done with them. Hezekiah told the truth and put his actions in the best light, but he did not relate what the envoys had said or explain his motive. He put the best possible light on his actions. Nevertheless he put his own neck in the noose by answering Isaiah's simple questions as he did (cf. Gal. 6:7).
39:5-6 Isaiah informed the king that the Babylonians would end up taking everything that Hezekiah had shown the ambassadors back to Babylon--not as resources for opposition to Assyria but as the spoils of war.381The ambassadors had come "from Babylon"(v. 3), but they would carry everything off "to Babylon"(v. 6). Hezekiah had shown them "all"(v. 4), but they would take "all"(v. 6, twice) to Babylon. This happened finally in 586 B.C. when Nebuchadnezzar captured Jerusalem (cf. 2 Kings 24:13; 25:13-15; 2 Chron. 36:18; Jer. 20:5). Isaiah's mention of Babylon as the enemy undoubtedly shocked Hezekiah because at this time Assyria was the great threat to Judah. Furthermore, Isaiah had previously predicted the demise of Babylon (ch. 14).
". . . Isaiah's message to Hezekiah is the same as it was to Ahaz, whose trust was in Assyria. That which we trust in place of God will one day turn and destroy us.'"382
This one sin of Hezekiah's did not doom Judah to Babylonian captivity. However, it illustrates the pride that the whole nation and its leaders manifested that ultimately resulted in the captivity.
39:7 Some of Hezekiah's descendants would also be taken (captive) to Babylon.383This became true of the king's physical descendants: his son Manasseh (2 Chron. 33:11), King Jehoiachin (2 Kings 24:12), and King Zedekiah (2 Kings 25:7). It also became true of many of Hezekiah's people, his children in that sense, when Nebuchadnezzar carried three deportations of Judahites off to Babylon (cf. 2 Kings 24:12-16; 2 Chron. 33:11; Dan. 1:3-4, 6).
39:8 Hezekiah's response to Isaiah's announcement of God's punishment for his lack of faith was deeply disappointing. Formerly when Isaiah had announced coming divine judgment the king had mourned and fasted (38:1-2), and God had relented (38:5-6). This time Hezekiah simply rejoiced that it would not come in his lifetime.384The king acknowledged that Judah deserved divine judgment, but his lack of concern for his people's welfare shows that he did not really have the heart for them that the predicted Davidic ruler would need to rule in righteousness. Hezekiah could not be the promised child of 7:14.
The chronological relationship of the events in chapters 36-39 is difficult to understand, but clearly all these events happened at about the same time, probably within a year or two.385During this period Hezekiah trusted God twice and failed to trust God once. This should teach us that it is possible for a person to trust God in very difficult circumstances and turn right around and trust in people and things with the next temptation. We need to demonstrate consistent trust in the Lord, by His grace. We can do this by maintaining a daily intimate relationship with Him marked by humility and prayer. We also need to learn not to trust in human leaders, because their faith wavers, but in the Lord Himself, whose faithfulness never varies.
". . . chs. 36-39 make chs. 40-66 a necessity. Given that God may be trusted, what then? Given that salvation is not in Hezekiah, where is it? Given that one-time trust is not enough, how is a life of continuous trust possible? Given that the best of God's people fail, where is our hope?"386
