《资治通鉴·汉纪·汉纪四十八》
过去，春秋时代，邢国暴虐无道，卫国对它进行讨伐，大军出动之日，上天及时降雨。我率军征战，经过夏天，接连获降及时雨，庄稼丰收，人民也没有瘟疫疾病。
昔邢为无道，卫国伐之，师兴而雨；臣动兵涉夏，连获甘澍，岁时丰稔，人无疵疫。
In the past, during the Spring and Autumn Period, Xing State was cruel and lawless, so Wei State attacked it. When the army started to set out, the heaven timely rained. When I led the army to fight, it keeps raining during the summer, and as a result, crops grow well and people do not get infected by diseases.
