《资治通鉴·唐纪·唐纪三十九》
从十月初一日颁下诏书征调诸道军队以来，已有四十天，但是没有一兵一卒入关赴难，这是地方背叛陛下。
自十月朔召诸道兵，尽四十日，无只轮入关，此四方叛陛下也。
Since the edict was issued on the first day of October to mobilize the troops of all roads, it has been forty days, but no one has entered the pass to help, which is the betrayal of the local government to the emperor.
