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.
Thy sons that shall issue from thee - the sons which Hezekiah (as Josephus tells us) wished to have (note, Isaiah 37:3, on "wept sore") will be among the foremost in suffering.
Eunuchs - fulfilled, Daniel 1:2-3; Daniel 1:7.
