2 Kings 20:12, 13

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

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