2 Kings 20:12-13

12Soon after this, Merodach-baladan son of Baladan, king of Babylon, sent Hezekiah his best wishes and a gift, for he had heard that Hezekiah had been very sick.

13Hezekiah received the Babylonian envoys and showed them everything in his treasure-houses—the silver, the gold, the spices, and the aromatic oils. He also took them to see his armory and showed them everything in his royal treasuries! There was nothing in his palace or kingdom that Hezekiah did not show them.
