2.13

若大深不異於行潦。則孺子浴其淵（孺子。說文乳子也。若江之遠深海之廣闊。而不異於行潦。則食乳之子。亦可洗濯）。

If great depth were no different from a flowing puddle, then suckling infants could bathe in its depths. (For 'infant' [ruzi], the Shuowen says a suckling child. If the expanse and depth of the Yangtze and the ocean were no different from a puddle, then a child taking milk could also wash in them.)
