《旧唐书·列传·卷三十七》
以亲人而言，天皇是陛下的丈夫，皇嗣是陛下的亲子，陛下应当将皇位传之子孙，以为万代之计。
以亲亲言之，则天皇是陛下夫也，皇嗣是陛下子也，陛下正合传之子孙，为万代计。
In terms of kinship, His Majesty the Emperor is Your Majesty's husband, and His Majesty the Crown Prince is Your Majesty's own son, Your Majesty should pass the throne to your descendant, so as to provide for future generations.
