2 Chronicles 32:27-31

And Hezekiah had exceeding much riches and honor: and he provided him treasuries for silver, and for gold, and for precious stones, and for spices, and for shields, and for all manner of goodly vessels; store-houses also for the increase of grain and new wine and oil; and stalls for all manner of beasts, and flocks in folds. Moreover he provided him cities, and possessions of flocks and herds in abundance; for God had given him very much substance. This same Hezekiah also stopped the upper spring of the waters of Gihon, and brought them straight down on the west side of the city of David. And Hezekiah prospered in all his works. Howbeit in the business of the ambassadors of the princes of Babylon, who sent unto him to inquire of the wonder that was done in the land, God left him, to try him, that he might know all that was in his heart.
