פירוש על מלכים ב 20:18

And some of your sons. Chananyoh, Mishoeil, and Azaryoh.²²Some say that they were eunuchs, because it was the custom to castrate those who served in the palace. Targum maintains that סריסים means ‘officers.’ It is merely a figurative expression used here to symbolize that paganism's impotence was acknowledged in their time. Chananyoh, Mishoeil and Azaryoh would risk their lives by defying the order to worship idols and be miraculously saved. See Maseches Sanhedrin 93b.
