《资治通鉴·唐纪·唐纪四十七》
而且，现在河东的全部兵马都在安邑屯驻，马燧来到朝廷。希望陛下敕令马燧与我同时向陛下辞别，一起离开长安，使陕虢人打算侵害我时，便害怕河东调动军队讨伐他们，这也算是一种声势吧。 
且今河东全军屯安邑，马燧入朝，愿敕燧与臣同辞皆行，使陕人欲加害于臣，则畏河东移军讨之，此亦一势也。 
Moreover, all of the soldiers and horses of Hedong are currently stationed at Anyi. Ma Sui has come to the court. I hope your majesty will order Ma Sui to say goodbye to your majesty at the same time as me, and that we depart from Chang’an together. In this way, when the people of Shaan and Guo plan to harm me, they will fear that the army of Hedong will mobilize and punish them. This can also be considered a show of strength.
