Isaiah 39:7

And some of your own sons , who will come from you, whom you will father , shall be taken away , and they shall be eunuchs in the palace of the king of Babylon .

And some of your descendants, your own flesh and blood who will be born to you, will be taken away, and they will become eunuchs in the palace of the king of Babylon.”

And of thy sons that shall issue from thee, which thou shalt beget, shall they take away; and they shall be eunuchs in the palace of the king of Babylon.
