Reply To: Chidushim on Daf Yomi Shabbos 30

Jumping ahead for our purpose, there is an argument on daf 40 about putting up water to warm what the expression יד סולדת בו, the hand burning, means. First of all, the gemora says there that it means the scorching of a babies stomach an not the hand which comes before the hand. Second, there is an argument between Rashi and the Rosh about its meaning. Rashi says that it is dependent on the time the pot is on the fire whereas the Rosh says it is dependent on the place whether it can scorch.
