II Kings 20:16-18

Then Isaiah said to Hezekiah, “Hear the word of the LORD: ‘Behold, the days are coming when all that is in your house, and what your fathers have accumulated until this day, shall be carried to Babylon; nothing shall be left,’ says the LORD. ‘And they shall take away some of your sons who will descend from you, whom you will beget; and they shall be eunuchs in the palace of the king of Babylon.’ ”
