《周书·列传·卷十二》
到大军将要出发时，宇文宪上表献出自己的财产以赞助军费说： 我听说把握机会适应气运，理应藉助时机的到来，兼并弱小攻击愚昧，要凭藉随机应变的谋略。
及大军将出，宪表上私财以助军费曰： 臣闻抚机适运，理藉时来，兼弱攻昧，事资权道。
When the army was about to set out, Yuwen Xian presented a memorial offering his own property to sponsor the military expenses, saying: I heard that seizing the opportunity to adapt to the luck, should make use of the arrival of the time, annexing the weak and attacking the foolish, relying on the strategy of adapting to the situation.
