Pesahim 18
· Rabbi Meir and Rabbi Eliezer – liquids do not transmit impurity
· Rabbi Yose and Rabbi Shimon – liquids transmit only to food
· Rabbi Yehuda – liquids transmit to vessels and food
Rabbi Yehuda retracted – fully or still say transmit to food?
Attempted proof from Parah of full retraction
Rabbi Yose’s proof
Rabbi Akiva learned from יטמא (v. 33) that food -> shelishi to food
So too Rabbi Yose – יטמא (v. 34b) liquid -> food
34a and 34b apply food->liquid and liquid->food
But maybe verse teaches liquid -> vessels?
Even vessels don’t -> vessels
יטמא (v. 34a) – food -> liquid
But maybe verse teaches food -> vessels?
No, liquids are just susceptible
Principle of food->liquid, liquid->food from v. 38
