From the Talmud (Shabbat 156b) (Soncino Translation):
From R. Akiba too [we learn that] Israel is free from planetary influence. For R. Akiba had a daughter. Now, astrologers told him, On the day she enters the bridal chamber a snake will bite her and she will die. He was very worried about this. On that day [of her marriage] she took a brooch [and] stuck it into the wall and by chance it penetrated [sank] into the eye of a serpent. The following morning, when she took it out, the snake came trailing after it. ‘What did you do?’ her father asked her. ‘A poor man came to our door in the evening.’ she replied, ‘and everybody was busy at the banquet, and there was none to attend to him. So I took the portion which was given to me and gave it to him. ‘You have done a good deed,’ said he to her. Thereupon R. Akiba went out and lectured: ‘But charity delivereth from death’: and not [merely] from an unnatural death, but from death itself.
Was Rabbi Akiva obligated to tell his daughter's potential suitor that an astrologer had foretold that she would die on the day of her marriage?
