Isaiah 39:1-2

1At 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 and had recovered.

2Hezekiah was pleased with the letters, and he showed the envoys his treasure house — the silver, the gold, the spices, and the precious oil — and all 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.
