2 Kings 20:16-18

16Then Isaiah said to Hezekiah, “Hear the word of the Lord:

17‘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.

18‘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.’”
