Isaiah 39:1; Isaiah 39:6

1 At that time Merodakh-Bal'odan the son of Bal'adan, king of Bavel, sent letters and a present to Hizkiyahu; for he heard that he had been sick, and was recovered.
6 Behold, the days are coming, when all that is in your house, and that which your fathers have laid up in store until this day, shall be carried to Bavel: nothing shall be left, says the LORD.
