After these things and this faithfulness, Sennacherib king of Assyria came and invaded Judah and besieged the fortified cities, intending to take them for himself. When Hezekiah saw that Sennacherib had come and that he intended to go to war against Jerusalem, he decided, together with his officers and his soldiers, to stop up the water [supply] from the springs which were outside the city [by enclosing them with masonry and concealing them], and they helped him. So many people came together, and they stopped up all the springs and the brook which flowed [underground] through the region, saying, “Why should the kings of Assyria come and find an abundance of water?” Also Hezekiah resolutely set to work and rebuilt all the wall that had been broken down, and erected towers on it, and he built another wall outside and strengthened the Millo (fortification) in the City of David, and made a great number of weapons and shields. He also appointed military officers over the people and gathered them to him in the square at the city gate, and spoke encouragingly to them, saying, “Be strong and courageous. Do not fear or be dismayed because of the king of Assyria, nor because of all the army that is with him; for the One with us is greater than the one with him. With him there is only an arm of flesh, but with us is the LORD our God to help us and to fight our battles.” And the people relied on the words of Hezekiah king of Judah.
After this, Sennacherib king of Assyria, while he was at Lachish [besieging it] with all his forces, sent his servants to Jerusalem, to Hezekiah king of Judah, and to all Judah who were at Jerusalem, saying, “Thus says Sennacherib king of Assyria, ‘In what do you trust that you are remaining in Jerusalem under siege? Is not Hezekiah misleading you in order to let you die by famine and thirst, while saying, “The LORD our God will rescue us from the hand of the king of Assyria?” Has the same Hezekiah not taken away his [Baal’s] high places and his altars, and commanded Judah and Jerusalem, “You shall worship before [only] one altar and burn incense on it”? Do you not know what I and my fathers (ancestors) have done to all the peoples of the [other] lands? Were the gods of the nations of those lands able to rescue their lands from my hand at all? Who [was there] among all the gods of those nations that my fathers utterly destroyed who was able to rescue his people from my hand, that your God should be able to rescue you from my hand? So now, do not let Hezekiah deceive or mislead you like this, and do not believe him, for no god of any nation or kingdom has been able to rescue his people from my hand or the hand of my fathers. How much less will your God rescue you from my hand!’ ”
And his servants said even more against the LORD God and against His servant Hezekiah. The Assyrian king also wrote letters insulting and taunting the LORD God of Israel, and speaking against Him, saying, “As the gods of the nations of other lands have not rescued their people from my hand, so the God of Hezekiah will not rescue His people from my hand.” They shouted it loudly in the language of Judah to the people of Jerusalem who were on the wall, to frighten and terrify them, so that they might take the city [without a long siege]. They spoke of the God of Jerusalem as [they spoke of] the gods of the peoples of the earth, [which are only] the work of the hands of men.
But Hezekiah the king and the prophet Isaiah the son of Amoz prayed about this and cried out to heaven [for help]. And the LORD sent an angel who destroyed every brave warrior, commander, and officer in the camp of the king of Assyria. So the king returned to his own land in shame. And when he entered the house (temple) of his god, some of his own children killed him there with the sword. [2 Kin 19:35-37] Thus the LORD saved Hezekiah and the inhabitants of Jerusalem from the hand of Sennacherib the king of Assyria and from the hand of all others, and He gave them rest on every side. And many brought gifts to the LORD at Jerusalem and valuable presents to Hezekiah king of Judah; so from then on he was exalted in the sight of all nations.
