2 Chronicles 32:21-25

And the Lord sent an angel who destroyed every warrior, commander, and officer in the camp of the king of Assyria. So he returned in shame to his own land. And when he had entered the temple of his god, some of his own sons killed him there with the sword.

So 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 guided them on every side.

And many were bringing gifts to the Lord at Jerusalem and valuable presents to Hezekiah king of Judah; so thereafter he rose in the sight of all nations.

In those days Hezekiah became mortally ill; and he prayed to the Lord, and the Lord spoke to him and gave him a sign.

But Hezekiah did nothing in return for the benefit he received, because his heart was proud; therefore wrath came upon him and upon Judah and Jerusalem.
