《资治通鉴·晋纪·晋纪十一》
现在残留的晋朝还没有消灭，巴、蜀也不来朝见，石勒图谋占据赵、魏地区，曹嶷想在齐地称王，陛下的心腹四肢，哪一处没有危险呢？
今遗晋未殄，巴、蜀不宾，石勒谋据赵、魏，曹嶷欲王全齐，陛下心腹四支，何处无患！
Now the remnants of the Jin Dynasty have not yet been eliminated, Ba and Shu have not come to pay their respects, Shi Le plotted to occupy the Zhao and Wei regions, Cao Yu planned to proclaim himself king in Qi, which of Your Majesty's key limbs is not in danger?
