2 Chronicles 32:24-31

In those days Hezekiah became terminally ill; and he prayed to the LORD, and He answered him and gave him a [miraculous] sign. But Hezekiah did nothing [for the LORD] in return for the benefit bestowed on him, because his heart had become proud; therefore God’s wrath came on him and on Judah and Jerusalem. However, Hezekiah humbled his proud heart, both he and the inhabitants of Jerusalem, so that the wrath of the LORD did not come on them during the days of Hezekiah. Now Hezekiah had immense wealth and honor; and he made for himself treasuries for silver, gold, precious stones, spices, shields, and all kinds of delightful articles, and storehouses for the produce of grain, new wine, and [olive] oil, and stalls for all kinds of cattle, and sheepfolds for the flocks. Moreover, he made cities for himself and acquired an abundance of flocks and herds, for God gave him very many possessions. This same Hezekiah also stopped up the upper outlet of the waters of Gihon and channeled them down to the west side of the City of David. Hezekiah succeeded in everything that he did. And so in the matter of the envoys of the rulers of Babylon, who were sent to him to inquire about the wonder that had happened in the land, God left him alone only to test him, in order to know everything that was in his heart. [Is 39:1-7]
