Isaiah 39:5-7

5Then Isaiah said to Hezekiah, “Hear the word of the Lord of Armies:

6‘Look, the days are coming when everything in your palace and all that your predecessors have stored up until today will be carried off to Babylon; nothing will be left,’ says the Lord.

7‘Some of your descendants — who come from you, whom you father — will be taken away, and they will become eunuchs in the palace of the king of Babylon.’”
