《史记·十二本纪·项羽本纪》
长史司马欣，从前做栎阳狱掾，曾对项梁有过恩德；都尉董翳，最初劝说章邯降楚，所以封司马欣为塞王，称王于咸阳以东到黄河一带，建都栎阳；封董翳为翟王，称王于上郡，建都高奴。
长史欣者，故为栎阳狱掾，尝有德於项梁；都尉董翳者，本劝章邯降楚。故立司马欣为塞王，王咸阳以东至河，都栎阳；立董翳为翟王，王上郡，都高奴。
The Recorder-Historian Sima Xin had previously been a prison warden at Liyang, and had done Xiang Liang a favor; Colonel Dong Yi had originally persuaded Zhang Han to capitulate to Chu, so they made Sima Xin King of Sai, titled him King of what was east of Xianyang as far as the Yellow River, and installed his capital at Liyang; and made Dong Yi King of Di, titled him King of Shangjun, and installed his capital at Gaonu.
