    秦将王翦破赵，虏赵王，尽收其地，进兵北略地，至燕南界。

    太子丹恐惧，乃请荆卿曰：“秦兵旦暮渡易水，则虽欲长侍足下，岂可得哉？”荆卿曰：“微太子言，臣愿得谒之。今行而无信，则秦未可亲也。夫今樊将军，秦王购之金千斤，邑万家。诚能得樊将军首，与燕督亢之地图，献秦王，秦王必说见臣，臣乃得有以报太子。”太子曰：“樊将军以穷困来归丹，丹不忍以己之私，而伤长者之意，愿足下更虑之！”

    荆轲知太子不忍，乃遂私见樊於期，曰：“秦之遇将军，可谓深矣。父母宗族，皆为戮没。今闻购樊将军之首，金千斤，邑万家，将奈何？”樊将军仰天太息流涕曰：“吾每念，常痛于骨髓，顾计不知所出耳！”轲曰：“今有一言，可以解燕国之患，报将军之仇者，何如？”於期乃前曰：“为之奈何？”荆轲曰：“愿得将军之首以献秦，秦王必喜而善见臣。臣左手把其袖，而右手揕其胸，然则将军之仇报，而燕国见陵之耻除矣。将军岂有意乎？”樊於期偏袒扼腕而进曰：“此臣之日夜切齿拊心也，乃今得闻教！”遂自刎。

    太子闻之，驰往，伏尸而哭，极哀。既已，不可奈何，乃遂盛樊於期之首，函封之。

    于是太子预求天下之利匕首，得赵人徐夫人之匕首，取之百金，使工以药淬之。以试人，血濡缕，人无不立死者。乃为装遣荆轲。
