2 Kings 18-20

Pride goes before a fall.

At that time Marduk-Baladan son of Baladan king of Babylon sent Hezekiah letters and a gift, because he had heard of Hezekiah’s illness. Hezekiah received the envoys and showed them all that was in his storehouses—the silver, the gold, the spices and the fine olive oil—his armory and everything found among his treasures. There was nothing in his palace or in all his kingdom that Hezekiah did not show them. (2 Kings 20:12-13)

Hezekiah seems too eager to display his wealth to the visitors from Babylon. In a display of pride he puts information and temptation before those representing Babylon. The envoys will go back to their own land, and sooner or later, Babylonian troops will return to Jerusalem in order to take away Hezekiah's treasures.
