2 Kings 20:18

And as for thy sons which shall come forth of thee, which thou shalt beget, [the enemy] shall take them, and they shall be eunuchs in the house 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.

‘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.’”
