《汉书·传·傅常郑甘陈段传》
太中大夫谷永上奏书为陈汤辩冤说道： 臣下听说楚国有子玉得臣，晋文公因为他而坐不安稳；趟国有廉颇、马服，强大的秦国不敢图谋井陉；近代汉朝有郅都、魏尚，匈奴就不敢越过沙漠南下。
太中大夫谷永上疏讼汤曰： 臣闻楚有子玉得臣，文公为之仄席而坐；赵有廉颇、马服，强秦不敢窥兵井陉；近汉有郅都、魏尚，匈奴不敢南乡沙幕。
Taizhong Dafu Gu Yong petitioned to defend Chen Tang: I heard that the State of Chu had a son of Yu Dechen, and Duke Wen of Jin was uneasy because of him; the State of Tang had Lian Po and Ma Fu, and the powerful State of Qin did not dare to plot Jingxing; in recent times, the Han Dynasty had Zhi Du and Wei Shang, and the Huns did not dare to cross the desert southward.
