Isaiah 39:1-2

1At that time Merodach-baladan the son of Baladan, king of Babylon, sent envoys with letters and a present to Hezekiah, for he heard that he had been sick and had recovered.

2And Hezekiah welcomed them gladly. And he showed them his treasure house, the silver, the gold, the spices, the precious oil, his whole armory, all that was found in his storehouses. There was nothing in his house or in all his realm that Hezekiah did not show them.
