2 Chronicles 32:8-9, 21

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

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]
