Hezekiah "trusted in the LORD God of Israel; so that after him was none like him among all the kings of Judah, nor any that were before him. For he clave to the LORD, and departed not from following him, but kept his commandments, which the LORD commanded Moses. And the LORD was with him.” If we looked only upon the surface, we might have considered that the piety of Hezekiah would have been rewarded in the exaltation of the nation over which be reigned. That his reign was very greatly beneficial to his subjects we freely admit. When, however, we draw a comparison between the days of Jehoshaphat and those of Hezekiah, we are struck by certain sure signs that, notwithstanding the latter's godliness, the nation has declined to a much lower footing before the Lord.
On the Assyrian coming upon the scene, Hezekiah proclaims no fast, as did Jehoshaphat; instead of the nation standing before the Lord, its godly king enters the sanctuary to make his own earnest prayer as an individual. In a day of national adversity, we read of two individuals, simply, as praying and crying to heaven (2 Chron. 32:20). Hezekiah indeed spread Sennacherib's letter before the Lord, but instead of an instant answer, the reply is sent by Isaiah to him (2 Kings 19:20). Then the army of Judah is in no way associated with the overthrow of the Assyrians, and instead of gathering spoil, poor Hezekiah had already endured the mortification of humbling himself before his enemy (2 Kings 18:14) and, what must have grieved him not less, of the sanctuary despoiled of silver and gold, in a vain attempt to satisfy the greed of his powerful adversary (vss. 15-16).
Had Hezekiah been content to set his house in order and die, the nation had been spared much suffering. During those added fifteen years was born Manasseh (2 Kings 21:1); the heart of Hezekiah became lifted up, to his own and to the nation's hurt (2 Chron. 32:25-26).
