2 Chronicles 32:23-25

23 And many brought gifts to the LORD at Jerusalem and valuable presents to Hezekiah king of Judah; so from then on he was exalted in the sight of all nations.

24 In those days Hezekiah became terminally ill; and he prayed to the LORD, and He answered him and gave him a [miraculous] sign.

25 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.
