Isaiah 39:1; Isaiah 39:6

1 M'rodakh-Bal'adan the son of Bal'adan, king of Bavel, heard that Hizkiyahu had been ill and had recovered, so he sent a letter and a gift to him.
6 'The day will come when everything in your palace, along with everything your ancestors stored up until today, will be carried off to Bavel. Nothing will be left,' says ADONAI.
