《汉书·传·叙传上》
班氏奉是颛项的后裔，家世中叶在楚国显出赫赫神灵，楚亡后离开了故土，又雄据北方晋、代之地远扬声名。
系高顼之玄胄兮，氏中叶之炳灵，由凯风而蝉蜕兮，雄朔野以飏声。
The Ban clan descends from Zhuan Xu. In the middle of its lineage, there was a glorious manifestation of deities in the state of Chu. After the Chu was destroyed, they left their homeland and settled in the northern state of Jìn and Dài, where they became greatly distinguished.
