Isaiah 39:1-2

1At that time Merodach-baladan son of Baladan king of Babylon sent letters and a gift to Hezekiah, for he had heard about Hezekiah’s illness and recovery. 2And Hezekiah welcomed the envoys gladly and showed them what was in his treasure house—the silver, the gold, the spices, and the precious oil, as well as his entire armory—all that was found in his storehouses. There was nothing in his palace or in all his dominion that Hezekiah did not show them.
