2 Chronicles 32:27-31

32:27 Hezekiah was very wealthy and greatly respected. He made storehouses for his silver, gold, precious stones, spices, and all his other valuable possessions. 32:28 He made storerooms for the harvest of grain, wine, and olive oil, and stalls for all his various kinds of livestock and his flocks. 32:29 He built royal cities and owned a large number of sheep and cattle, for God gave him a huge amount of possessions.

32:30 Hezekiah dammed up the source of the waters of the Upper Gihon and directed them down to the west side of the City of David. Hezekiah succeeded in all that he did. 32:31 So when the envoys arrived from the Babylonian officials to visit him and inquire about the sign that occurred in the land, God left him alone to test him, in order to know his true motives.
