II Chronicles 32:24-31

In those days Hezekiah was sick and near death, and he prayed to the LORD; and He spoke to him and gave him a sign. But Hezekiah did not repay according to the favor shown him, for his heart was lifted up; therefore wrath was looming over him and over Judah and Jerusalem. Then Hezekiah humbled himself for the pride of his heart, he and the inhabitants of Jerusalem, so that the wrath of the LORD did not come upon them in the days of Hezekiah. Hezekiah had very great riches and honor. And he made himself treasuries for silver, for gold, for precious stones, for spices, for shields, and for all kinds of desirable items; storehouses for the harvest of grain, wine, and oil; and stalls for all kinds of livestock, and folds for flocks. Moreover he provided cities for himself, and possessions of flocks and herds in abundance; for God had given him very much property. This same Hezekiah also stopped the water outlet of Upper Gihon, and brought the water by tunnel to the west side of the City of David. Hezekiah prospered in all his works. However, regarding the ambassadors of the princes of Babylon, whom they sent to him to inquire about the wonder that was done in the land, God withdrew from him, in order to test him, that He might know all that was in his heart.
