2 Kings 20:16

14Then Isaiah the prophet came to King Hezekiah, and said to him, “What did these men say? From where did they come to you?” Hezekiah said, “They have come from a far country, even from Babylon.”

15He said, “What have they seen in your house?” Hezekiah answered, “They have seen all that is in my house. There is nothing among my treasures that I have not shown them.”

16Isaiah said to Hezekiah, “Hear the LORD’s word.

17‘Behold, the days come that all that is in your house, and that which your fathers have laid up in store to this day, will be carried to Babylon. Nothing will be left,’ says the LORD.

18‘They will take away some of your sons who will issue from you, whom you will father; and they will be eunuchs in the palace of the king of Babylon.’”
