The Art of War (孫子兵法), Energy 埶篇

故善出奇者無窮如天地不竭如江河終而復始日月是也死而復生四時是也

Indirect tactics, efficiently applied, are inexhaustible as Heaven and Earth, unending as the flow of rivers and streams;

like the sun and moon, they end but to begin anew; like the four seasons, they pass away but to return once more.

Lionel Giles's notes

奇 is the universally accepted emendation for 兵, the reading of the 北堂書鈔.

Tu Yu and Chang Yü understand this of the permutations of 奇 and 正. But at present Sun Tzŭ is not speaking of 正 at all, unless, indeed, we suppose with 鄭友賢 Chêng Yu-hsien that a clause relating to it has fallen out of the text. Of course, as has already been pointed out, the two are so inextricably interwoven in all military operations, that they cannot really be considered apart. Here we simply have an expression, in figurative language, of the almost infinite resource of a great leader.
