《史记·三十世家·陈涉世家》
那个时候，商鞅辅佐秦孝公，对内建立法令制度，致力于耕种纺织，整治攻守的武器，对外用连横的策略使诸侯们互相争斗。
当是时也，商君佐之，内立法度，务耕织，修守战之备；外连衡而斗诸侯。
At that time, Shang Yang assisted King Xiao of Qin, established laws and ordinances internally, focused on farming and textile production, and reorganized offensive and defensive weapons. Externally, he used a strategy of vertical and horizontal alliances to cause the feudal lords to fight each other.
