Isaiah 39:1-2

1At that time Marduk-Baladan son of Baladan king of Babylon sent Hezekiah letters and a gift, because he had heard of his illness and recovery.

2Hezekiah received the envoys gladly and showed them what was in his storehouses—the silver, the gold, the spices, the fine olive oil—his entire armory and everything found among his treasures. There was nothing in his palace or in all his kingdom that Hezekiah did not show them.
