不革（古文革[懂-重+(巫/十)]諽三形同古核反革更也謂改更也說文獸去毛曰革言治去毛變更之也故字從囗囗為國邑國三十年而法更別取別異之意也囗音韋）。

Not altering (不革: the ancient script for 革 has three forms, 革, [懂-重+(巫/十)], and 諽, all the same; pronounced [gu + he >] *gé*. 革 means to change, that is, to alter and renew. The Shuowen jiezi states: "Animal skin stripped of hair is called 革"; it means removing the hair through processing to transform and change it. Thus the character contains 囗; 囗 represents a city-state: after thirty years in a state, the laws are changed, taking the sense of distinction and difference. 囗 is pronounced *wéi*).
