承叶八正末句:那人就这条诫命而论仍是十足的义人——求赏这一层私意并不折损诫命的分量。答:所虑的是他搜完酵、诫命已行毕之后再去找针;诫命既已行毕,其功德便护不住他了。

——那人就这条诫命而论,岂不仍是十足的义人么?
this person is a full-fledged righteous person as far as that mitzva is concerned?
-
求赏这一类私意,并不折损那条诫命的分量。
These ulterior motives, e.g., seeking a reward, do not detract from the value of the mitzva.

革玛拉答:所虑的仍是他搜完了酵、把搜查办毕之后,再去找那根针。
The Gemara answers: There is still concern lest he look for the needle after he searched for leaven and completed the search.
-
那时危险就在于:诫命既已行毕,他找针时便没有那功德护着他了。
There is danger that since he already completed the mitzva, its merit will not protect him when he is searching for the needle.
