《资治通鉴·秦纪·秦纪一》
可是赵王坚持着非要让他重新出马不可，李牧无奈，便说： 如果一定要用我，必须允许我仍照从前的办法行事，我才敢接受您的命令。 
王强起之，李牧曰： 必用臣，臣如前，乃敢奉令。 
But King Zhao insisted that he come out again, and Li Mu had no choice but to say: If you must use me, you must allow me to act according to my previous methods, and only then will I dare to accept your orders.
