Isaiah 39:2 (KJV)

At that time Merodach–baladan, the son of Baladan, king of Babylon, sent letters and a present to Hezekiah: for he had heard that he had been sick, and was recovered.

And Hezekiah was glad of them, and shewed them the house of his precious things, the silver, and the gold, and the spices, and the precious ointment, and all the house of his armour, and all that was found in his treasures: there was nothing in his house, nor in all his dominion, that Hezekiah shewed them not.

Then came Isaiah the prophet unto king Hezekiah, and said unto him, What said these men? and from whence came they unto thee? And Hezekiah said, They are come from a far country unto me, even from Babylon.

Then said he, What have they seen in thine house? And Hezekiah answered, All that is in mine house have they seen: there is nothing among my treasures that I have not shewed them.
