《汉书·传·匈奴传下》
汉天子下诏报知单于说： 夏侯藩擅自假托天子诏旨向单于索要土地，按法应当处死，经过两次大赦，现在把夏侯藩迁为济南太守，不让他再驻扎在面向匈奴的地方。 
诏报单于曰： 藩擅称诏从单于求地，法当死，更大赦二，今徙藩为济南太守，不令当匈奴。 
The Han Emperor issued an edict to inform the Chanyu, saying: Xiahou Fan presumptuously used the Emperor's edict to ask the Chanyu for land, according to the law he should be executed, but through two major amnesties, now Xiahou Fan is transferred to be Prefect of Jinan, and he cannot be stationed at a place facing the Xiongnu.
