2 Kings 20:12-15

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

13And Hezekiah was attentive to them, and showed them all the house of his treasures—the silver and gold, the spices and precious ointment, and all his armory—all that was found among his treasures. There was nothing in his house or in all his dominion that Hezekiah did not show them.

14Then Isaiah the prophet went to King Hezekiah, and said to him, “What did these men say, and from where did they come to you?” So Hezekiah said, “They came from a far country, from Babylon.”

15And he said, “What have they seen in your house?” So Hezekiah answered, “They have seen all that is in my house; there is nothing among my treasures that I have not shown them.”
