2 Kings 20:12-13

12At that time Berodach-baladan, son of King Baladan of Babylon, sent a letter and a present to Hezekiah, for he had heard that Hezekiah had been sick.

13Now Hezekiah listened to them, and showed them his entire treasure house—the silver and the gold, the spices and the precious oil—and his armory, and everything that was found in his treasuries. There was nothing in his house or in all his dominion that Hezekiah did not show them.
