Ein AyahAvoid Overstepping the Boundaries of Trust
Ein Aya Shabbat Chapter B Paragraph 192
Rav would not pass in a ferry in which a non-Jew was sitting, as he would say: “Perhaps there is a decree upon him, and I may be affected along with him.” Shmuel would pass only in a ferry in which a non-Jew was sitting, as he would say: “Anger against the members of two nations will not have dominion.” Rabbi Yannai would check [for holes in the ferry – Rashi]. Rabbi Yannai was consistent in his approach, as he would say: “A person should never stand in a place of danger and assume that a miracle will happen to him, for not always is a miracle done for him, and if a miracle does occur, it is subtracted from his merits.”
