《孔子家语·执辔》
孔子说： 古代的天子把内史作为帮助自己执政的左右手，把德政和法制当做马的勒口，把百官当做缰绳，把刑罚当做马鞭，把万民当做马，所以统治天下数百年而没有失误。
孔子曰： 古者天子以内史为左右手，以德法为衔勒，以百官为辔，以刑罚为策，以万民为马，故御天下数百年而不失。
Confucius said: The ancient emperors regarded the inner historiographer as their helpers in their governance, regarded virtue and law as the bridle, regarded the officials as the reins, regarded the punishment as the whip, and regarded the masses as the horse, and thus they ruled the天下 for hundreds of years without any mistakes.
