2 Chronicles 32:27-31

And Hezekiah had very great riches and honor, and he made for himself treasuries for silver, for gold, for precious stones, for spices, for shields, and for all kinds of costly vessels; 28 storehouses also for the yield of grain, wine, and oil; and stalls for all kinds of cattle, and sheepfolds. 29 He likewise provided cities for himself, and flocks and herds in abundance, for God had given him very great possessions. 30 This same Hezekiah closed the upper outlet of the waters of Gihon and directed them down to the west side of the city of David. And Hezekiah prospered in all his works. 31 And so in the matter of the envoys of the princes of Babylon, who had been sent to him to inquire about the sign that had been done in the land, God left him to himself, in order to test him and to know all that was in his heart.
