But on our page there is a question as to whether any of this is necessary. Does possession have to be transferred?
It was stated: The food for the shittuf of alleys, Rab ruled, requires no transfer of possession, and Samuel ruled: It does require transfer of possession. . .
And so a story is told:
The question of transfer is a point at issue between Tannas. For Rab Judah related in the name of Rab: The daughter-in-law of R. Oshaia was once overtaken by dusk (on the eve of Shabbat) when she went to a bath house (beyond the Sabbath limit) and her mother-in-law prepared for her an ‘erub.
R. Hiyya to whom the incident was reported forbade her return. “Babylonian”, said R. Ishmael son of R. Jose to him, “are you so strict about the laws of ‘erub? Thus said my father: ‘Wherever you see an opportunity of relaxing the laws of ‘erub seize it!’”
The discussion then goes to the question of what the mother-in-law might have done wrong. Did she neglect to transfer the possession or was it that all was done without the daughter-in-law’s knowledge. In either case, though, the statement of R. Hiyya’s father is that the goal of eruv is to make people’s lives easier, not harder!
