2 Kings 20:12-13

At that time Merodach-Baladan son of Baladan was king of Babylon. He sent letters and a gift to Hezekiah, because he had heard that Hezekiah was sick. Hezekiah listened to the messengers, so he showed them what was in his storehouses: the silver, gold, spices, expensive perfumes, his swords and shields, and all his wealth. He showed them everything in his palace and his kingdom.
