《资治通鉴·汉纪·汉纪三十四》
因东光侯耿纯曾经当过东郡太守，在卫地很有威信，刘秀派使者任命耿纯当太中大夫，让他和李通、王常率领的大军在东郡会合。
以东光侯耿纯尝为东郡太守，威信著于卫地，遣使拜太中大夫，使与大兵会东郡。
Because Geng Chun, the Marquis of Dongguang, had once been the provincial governor of Dong County and held great prestige in the region of Wei, Liu Xiu sent an emissary to appoint Geng Chun as a grand palace counsellor, and had him join forces with the army led by Li Tong and Wang Chang in Dong County.
