《旧唐书·列传·卷十九》
众将请求趁机袭击他们，君集说 ：不行，天子因为高昌王骄慢无礼，派我奉命执行上天对他的惩罚，现在在坟墟墓地之间袭击他们，不是问罪之师。 
诸将请袭之，君集曰： 不可，天子以高昌骄慢无礼，使吾恭行天罚，今袭人于墟墓之间，非问罪之师也。 
The generals requested to use this opportunity to attack them, Junji said: No, the Emperor sent me to carry out the punishment from the heavens on the Gaochang King for his arrogance and disrespect, now between the tomb and the cemetery attacking them, this is not in line with a force that is inquiring into a crime.
