2 Chronicles 32:25 (KJV)

And for this cause Hezekiah the king, and the prophet Isaiah the son of Amoz, prayed and cried to heaven.

And the LORD sent an angel, which cut off all the mighty men of valour, and the leaders and captains in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he was come into the house of his god, they that came forth of his own bowels slew him there with the sword.

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 other, and guided them on every side.

And many brought gifts unto the LORD to Jerusalem, and presents to Hezekiah king of Judah: so that he was magnified in the sight of all nations from thenceforth.

In those days Hezekiah was sick to the death, and prayed unto the LORD: and he spake unto him, and he gave him a sign.

Notwithstanding Hezekiah humbled himself for the pride of his heart, both he and the inhabitants of Jerusalem, so that the wrath of the LORD came not upon them in the days of Hezekiah.

And Hezekiah had exceeding much riches and honour: and he made himself treasuries for silver, and for gold, and for precious stones, and for spices, and for shields, and for all manner of pleasant jewels;

Storehouses also for the increase of corn, and wine, and oil; and stalls for all manner of beasts, and cotes for flocks.

Moreover he provided him cities, and possessions of flocks and herds in abundance: for God had given him substance very much.

This same Hezekiah also stopped the upper watercourse of Gihon, and brought it straight down to the west side of the city of David. And Hezekiah prospered in all his works.
