2 Chronicles 32:27-31

Hezekiah had abundant riches and glory, and he made himself treasuries for silver, gold, precious stones, spices, shields, and every desirable item. He made warehouses for the harvest of grain, new wine, and fresh oil, and stalls for all kinds of cattle, and pens for flocks. He made cities for himself, and he acquired vast numbers of flocks and herds, for God gave him abundant possessions. This same Hezekiah blocked the upper outlet of the water from the Gihon Spring  and channeled it smoothly downward and westward to the city of David.  Hezekiah succeeded in everything he did. When the ambassadors of Babylon’s rulers  were sent  to him to inquire about the miraculous sign  that happened in the land, God left him to test him and discover what was in his heart.
