《左传·哀公·哀公十五年》
到了孔姬那里，吃完饭，孔姬手拿着戈走在前面，太子和五个人身披皮甲，用车装上公猪跟着，把孔悝逼到墙边，强迫他盟誓，于是就劫持他登上台去。
遂入，適伯姬氏。既食，孔伯姬杖戈而先，大子与五人介，舆豭从之。迫孔悝于厕，强盟之，遂劫以登台。
When they arrived at Kong Ji's house, after dinner, Kong Ji held a halberd in his hand and walked in front. The crown prince and five people put on armor, loaded the pigs on the cart, forced Kong Kui to the wall, forced him to take an oath, and then hijacked him onto the stage.
