2 Chronicles 32:27-31

Hezekiah was very wealthy and highly honored. He built special treasury buildings for his silver, gold, precious stones, and spices, and for his shields and other valuable items. He also constructed many storehouses for his grain, new wine, and olive oil; and he made many stalls for his cattle and pens for his flocks of sheep and goats. He built many towns and acquired vast flocks and herds, for God had given him great wealth. He blocked up the upper spring of Gihon and brought the water down through a tunnel to the west side of the City of David. And so he succeeded in everything he did. However, when ambassadors arrived from Babylon to ask about the remarkable events that had taken place in the land, God withdrew from Hezekiah in order to test him and to see what was really in his heart.
