2 Kings 20:11-13

11So the prophet Isaiah called out to the Lord, and he brought the shadow back the ten steps it had descended on the stairway of Ahaz.

12At that time Merodach-baladan son of Baladan, king of Babylon, sent letters and a gift to Hezekiah since he heard that he had been sick.

13Hezekiah listened to the letters and showed the envoys his whole treasure house — the silver, the gold, the spices, and the precious oil — and his armory, and everything that was found in his treasuries. There was nothing in his palace and in all his realm that Hezekiah did not show them.
