《北史·列传·卷二十六》
仁寿年间，裴肃见皇太子杨勇、蜀王杨秀、左仆射高赹都被罢黜，便派人给朝廷上书，说： 高赹是天赐的良才，国家的元勋，辅政的大臣，希望能记住他的大功，忘掉他的小过。
仁寿中，肃见皇太子勇、蜀王秀、左仆射高颎俱废黜，遣使上书，言： 高颎天挺良才，元勋佐命，愿录其大功，忘其小过。
During the Renshou period, when Pei Su saw that Crown Prince Yang Yong, Prince Yang Xiu of Shu, and Left Minister of State Affairs Gao Jiong had all been dismissed, he had someone submit a memorial to the imperial court, saying: Gao Jiong is a rare talent, a great contributor to the country, a great minister who assists in government affairs, and so on. He hoped that the emperor could remember his great contributions and forget his minor wrongdoings.
