2 Chronicles 32:27-31

Now Hezekiah had immense riches and honor; and he made for himself treasuries for silver, gold, precious stones, spices, shields and all kinds of valuable articles, storehouses also for the produce of grain, wine and oil, pens for all kinds of cattle and sheepfolds for the flocks. He made cities for himself and acquired flocks and herds in abundance, for God had given him very great wealth. It was Hezekiah who stopped the upper outlet of the waters of Gihon and directed them to the west side of the city of David. And Hezekiah prospered in all that he did. Even in the matter of the envoys of the rulers of Babylon, who sent to him to inquire of the wonder that had happened in the land, God left him alone only to test him, that He might know all that was in his heart.
