would be the difference between a Jew and non-Jew together tying tzitzis and
them together shechting an animal?
A. The case by shechting is where they are both holding onto the
knife when slaughtering where the Shulchan Aruch Yoreh Deah 2:11 says it is no
B. You need an action of a kosher shechita done by a Jew but it
does not transform the animal in any way but by tzitzis the four cornered
garment is transformed into a tzitzis garment and the action required to be
done by a Jew is just the means to transform it into a kosher tzitzis garment.
C. Why then would it be alright if a non-Jew made the tzitzis with the Jew even if it would not work by shechting the animal?
Answer: Since what is required by shechting is a kosher action then the whole action must be done only by a Jew according to the Shulchan Aruch. But by tzitzis you just need a garment of tzitzis made by a Jew and it was made by a Jew a non-Jew was just involved as well.
would a person be exempt for shooting an arrow at a guy holding a shield and
the shield was taken away from him right before it reaches him and he is
therefore hurt or even killed but in the same scenario if the arrow just
happens to properly, halachically slaughter a bird it is kosher?
A. The Gemara in Sanhedrin 77b says in the name of Rava
that because there was a shield in the way when the arrow was shot which would
have prevented harm then the fact it was removed before the arrow reached the
victim makes it indirect killing even if the shooter himself somehow removed
the shield before the arrow reached its target.
B. There is a Gemara in Chullin 30b about a case of
Rava checking Rebbe Yona bar Tachlifa’s arrows to make sure they were sharp
enough before being used to shoot and shecht birds in midflight.
C. The Gemara in Chullin 15b-16a says that one who
shechts using a knife powered by a water mill is not kosher because it is not
your direct power, rather it is secondary power of your which is causing the
slaughter to happen and therefore it is indirect and invalid.
D. By hurting or killing someone the sin is the act of killing or damaging.
E. The mitzvah of shechita does not need an act of shechita but that shechita comes from his power.
Answer: By the murder or injury we can say that it wasn’t his action of shooting that killed or hurt the person since the shield was in the way when the arrow was shot but by the slaughter, though the shechita would not have happened when the shield was there but it was taken away and it was because of the power of his shot that it was shechted properly therefore it is kosher.
