What does Isaiah 39:2 mean?

Hezekiah was pleased with the envoys and showed them everything in his treasure rooms—his silver, gold, spices, fine oils, his whole armory, and everything else he owned. There wasn’t anything in his palace or kingdom that he didn’t show them. Isaiah 39:2 - Modern Text Bible

(Hezekiah, perhaps flattered or wanting to impress, reveals all his wealth and resources to the Babylonian visitors.)
