Thanks gavra. I never learnt gemara, so if you have time, can you please explain? Thanks.
I don’t think that it would be correct to do so on an english language thread. It is not exactly something that should be known, lest it become a l’chatchila (IMHO).
Feel free to look into the Artscroll on the gemorah there, or the Shulchan Aruch if you don’t wnat to learn gemorah.
