承叶十八正末句:因挨着爬物而成不洁的液体,其不洁岂不正是由轻重推论而来?——因挨着器皿(那器皿是因挨着爬物才不洁的)而成不洁的液体尚且传不洁,那么直接因挨着爬物而成不洁的液体,岂不更该连器皿也传?

革玛拉问:因挨着爬物而成为不洁的液体,其不洁岂不正是由轻重推论而来的么——那因挨着器皿(那器皿是因挨着爬物才不洁的)而成为不洁的液体尚且传不洁,那么直接因挨着爬物而成为不洁的液体,岂不更该把不洁传给器皿么?
The Gemara asks: And doesn’t the impurity of liquids that came into contact with a creeping animal come from an a fortiori inference: Just as liquids that come to a state of impurity due to contact with a vessel, which itself became impure due to contact with a creeping animal, transmit impurity, with regard to liquids that come to a state of impurity due to contact with a creeping animal, all the more so is it not clear that they transmit impurity to a vessel?
