《汉书·传·匈奴传下》
王莽刚做天子，想凭恃国家府库的富有建立自己的威望，便封了十二部将帅，出动各郡县封国的勇士，拿出武器库的精良兵器，命他们各自驻扎在一方，逐渐向边塞输送。
莽新即位，怙府库之富欲立威，乃拜十二部将率，发郡国勇士，武库精兵，各有所屯守，转委输于边。
Wang Mang had just become emperor when he wanted to use the riches of the state vaults to establish his prestige, so he made twelve military commanders, mobilized the elite warriors of their feudal states, requisitioned weapons from the armories, ordered them to garrison places, and gradually sent them to the border.
