2 Chronicles 32:27-31

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. Howbeit in the business of the ambassadors of the princes of Babylon, who sent unto him to enquire 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.
