          十年春，齐师伐我。公将战。曹刿请见。其乡人曰：“肉食者谋之，又何间焉？”刿曰：“肉食者鄙，未能远谋。”乃入见。问：“何以战？”公曰：“衣食所安，弗敢专也，必以分人。”对曰：“小惠未徧，民弗从也。”公曰：“牺牲玉帛，弗敢加也，必以信。”对曰：“小信未孚，神弗福也。”公曰：“小大之狱，虽不能察，必以情。”对曰：“忠之属也。可以一战。战则请从。”
         公与之乘。战于长勺。公将鼓之。刿曰：“未可。”齐人三鼓。刿曰：“可矣。”齐师败绩。公将驰之。刿曰：“未可。”下视其辙，登轼而望之，曰：“可矣。”遂逐齐师。
         既克，公问其故。对曰：“夫战，勇气也。一鼓作气，再而衰，三而竭。彼竭我盈，故克之，夫大国，难测也，惧有伏焉。吾视其辙乱，望其旗靡，故逐之。
