正如 阿约 教导说:拉比犹大 说:人不能同时就两件事立条件,例如人不能在周五午后于两个不同的方向各立一个安息日界限的 合界,同时这样约定:明天安息日若有两位贤人从两个不同的方向来,我到那时再决定两位讲道的人中我愿意听哪一位——由此定下哪一个 合界 生效。
As Ayo taught that Rabbi Yehuda says: A person cannot stipulate conditions about two matters at once, e. g., one cannot establish a joining of Shabbat boundaries [eiruv] in each of two different directions on Friday afternoon while making the following stipulation: If tomorrow, on Shabbat, two Sages arrive from two different directions, I will decide then which of the two lecturers I prefer to hear at that point in time, which will determine which eiruv is in effect.
