2 Kings 20:12-15

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

13Hezekiah listened to and welcomed them and [foolishly] showed them all his treasure house—the silver and gold and spices and precious oil and his armory and everything that was found in his treasuries. There was nothing in his house (palace) nor in all his realm that Hezekiah did not show them.

14Then Isaiah the prophet came to King Hezekiah and said to him, “What did these men say [that would cause you to do this for them]? From where have they come to you?” Hezekiah said, “They have come from a far country, from Babylon.”

15Isaiah said, “What have they seen in your house?” Hezekiah answered, “They have seen everything that is in my house (palace). There is nothing in my treasuries that I have not shown them.”
