2 Chronicles 32:20

The prophet Isaiah. After the first attempt of the Assyrian envoys to discourage the people of Jerusalem, Hezekiah had sent a message to Isaiah urging him to pray to the Lord, and had received from the prophet the answer that the Lord would send a blast upon Sennacherib and cause him to return to his land (2 Kings 19:1-7). Then after the return of Rabshakeh to Sennacherib at Libnah, the envoys made their second visit (2 Kings 19:9-14), with further taunting messages from Sennacherib. Hezekiah took the letter into the Temple and earnestly besought the Lord for help, whereupon he received word from Isaiah that his prayer had been heard, that God would defend the city for David’s sake, and that Sennacherib would return home without laying siege to Jerusalem (2 Kings 19:14-34).
