In the olden days, kings and other nobles, observing the principle of noblesse oblige, fought at the heed of their troops.

昔日国王及其他的贵族们得遵守位高任重的原则，于故役中身先士卒。

Remote cousins and family friends whom mere acquaintanceship invested with a sort of blood obligation noblesse oblige.

仅仅是熟人关系的远房堂兄弟和家庭朋友就赋予了一种贵族义务的血缘义务。
