Yerushalmi Eruvin 2:7 ירושלמי עירובין ב׳:ז׳

MISHNAH: Rebbi Eliezer says, if its length exceeds its width even by one cubit one may not carry there¹³His reason is unknown. The statement is rejected in the Babli.. Rebbi Yose says, even if its length is twice its width one carries in there.

HALAKHAH: Paragraph. “Rebbi Jehudah says, even if it only contains a cistern,” etc. It was stated, “Rebbi Eliezer says, if its length exceeds its width even by one cubit one may not carry there¹³His reason is unknown. The statement is rejected in the Babli..” This disagrees with R. Jonathan⁹⁴Who said earlier (Note 81) that one inferred from the courtyard of the Tabernacle whose sides were in ratio 1:2.. “Rebbi Yose says, even if its length is twice its width one carries in there,” this agrees with Rebbi Jonathan. We also have stated⁹⁵The reference is to a statement close to Tosephta Kilaim 2:6: “How much is a bet rova`? 10.5 cubits square, Rebbi Yose says even if its length is twice its width.” The quarter is a quarter qav, 1/24 of a se’ah. Therefore a bet qav = 2500/24 = 104.1667 square cubits or 10.206², somewhat less than the 10.5² given in the Tosephta. The quote shows that R. Yose consistently considers “squares” mentioned in legal contexts as measures of area, rather than geometric squares., “Kilaim in a quarter⁹⁶Read רובע for רובה..
