人若弄错、一时在两个方向上都立了 合界,譬如他不明白,以为可以在两个方向上立 合界、把安息日所能走的路往相反两头都延出去;又或他对仆人说「你们出去替我立 合界」、并没有指明方向,一个替他在北边立了 合界,一个替他在南边立了 合界:那么他往北可走的路,以他南边那份 合界 所许的为限;往南可走的路,以他北边那份 合界 所许的为限。
If one erred and established an eiruv in two directions at once, for example, if in his ignorance he imagined that it is permitted to establish an eiruv in two directions, that he may extend the distance that he may walk on Shabbat in two opposite directions, or if he said to his servants: Go out and establish an eiruv for me, without specifying the direction, and one established an eiruv for him to the north, and one established an eiruv for him to the south, he may walk to the north as far as he is permitted go based on his eiruv to the south, and he may walk to the south as far as he is permitted go based on his eiruv to the north.
