《礼记·檀弓下》
卫君没有脱掉祭服就赶往柳庄家，于是就把身上穿的祭服脱下赠给死者，还将裘氏邑和潘氏县封给柳庄作采邑，又把这种封赏写成誓约放进棺里。誓约上写道： 世世代代子子孙孙，万代相传永不改变！ 
不释服而往，遂以襚之。与之邑裘氏与县潘氏，书而纳诸棺，曰： 世世万子孙，无变也。 
Wei did not take off his sacrificial clothing before going to Liu Zhuang's home, so he took off the sacrificial clothing he was wearing and gave it to the deceased, and also sealed the town of Qiu and the county of Pan to Liu Zhuang as fiefdoms, and put this reward into the coffin in writing. The solemn oath reads: From generation to generation, from generation to generation, it will never change!
