《战国策·秦五·四国为一将以攻秦》
更何况姚贾不过是魏都大梁一个守门人的儿子，曾在魏国作过盗贼，虽然在赵国作过官，后来却被驱逐出境，这样一个看门人的儿子、魏国的盗贼、赵国的逐臣，让他参与国家大事，不是勉励群臣的办法！ 
且梁监门子，尝盗于梁，臣于赵而逐。取世监门子，梁之大盗，赵之逐臣，与同知社稷之计，非所以厉群臣也。 
Moreover, Yao Jia was merely the son of a gatekeeper in Daliang, the capital of Wei. He was a bandit in Wei and had worked as an official in Zhao. Later, he was driven out of the country. As the son of a gatekeeper, a bandit in Wei, and a minister expelled from Zhao, it is not the way to encourage ministers to let him participate in major state affairs.
