《史记·三十世家·晋世家》
十九年，献公说： 当初我们的先君庄伯、武公平息晋国动乱时，虢国常常帮助晋国讨伐我们，又藏匿了晋国逃跑的公子，如果果真作乱，不去讨伐，将给子孙留下后患。 
十九年，献公曰： 始吾先君庄伯、武公之诛晋乱，而虢常助晋伐我，又匿晋亡公子，果为乱。弗诛，后遗子孙忧。 
In the 19th year, Duke Xian said: When our ancestors Zhuang Bo and Wu Ping pacified the turmoil in Jin, Guo often helped Jin to attack us, and also hid the escaped princes of Jin. If we really rebel, if we don't fight, it will leave future troubles for future generations.
