《淮南子·汜论训》
现在假设战场上两军对阵，两方将交战，将领于是下军令： 冲上前去斩下敌首的授予爵位，后退逃跑的腰斩。 
夫今陈卒设兵，两军相当，将施令曰： 斩首拜爵，而屈挠者要斩！ 
Now, suppose that on the battlefield two armies face each other in battle, and the two sides are about to engage. The general therefore gives the military order: whoever charges forward and cuts off the head of the enemy general will be enfeoffed, and whoever retreats and flees will be beheaded.
