2 Kings 20:16-18

Then Isaiah said to Hezekiah, “Listen to this message from the LORD: The time is coming when everything in your palace—all the treasures stored up by your ancestors until now—will be carried off to Babylon. Nothing will be left, says the LORD. Some of your very own sons will be taken away into exile. They will become eunuchs who will serve in the palace of Babylon’s king.”
