Superstition in Judaism
Superstition in Judaism refers to the credulous beliefs in the supernatural present in Judaism and Jewish culture. Judaism, unlike many of its contemporaries, lacks the framework for superstitious belief and often condemns it. Because idolatry was deeply connected to Canaanite and Bronze Age superstition, the Torah specifically warns against believing in lucky numbers and superstitious signs, as it can lead people away from God. However, following the Jewish diaspora, some Jewish communities partially adopted the superstitious customs of their neighbours.
Talmudic era
With the absolute acceptance of monotheism in the Talmudic era, superstition lost its idolatrous character and was no longer seen as a large threat, as it was in the Biblical era. That being said, superstition still remained a taboo, especially in communities in Babylon where superstition was pervasive. Many Tannaim and even Gaonim, implemented prohibitory laws against superstition, mostly in regards to shechita and marriage. Rav Ḥanina, for instance, answered a woman who desired to bewitch him stating that "It is written, There is none else beside Him'". In other words, Rav Hanina stated that the women's superstitious beliefs were foolish seeing as God has the final say in all things. The Talmud does however, contain some superstitious beliefs, in Pesachim 111b for example, it states "It is unwise to be between two dogs, two palms, or two women; and it is equally unwise for two men to be separated by one of these" although most Rabbis interpret this not as a superstition but rather to guard against lustful thoughts. In Pesachim 111a it states "It is dangerous to borrow a drink of water, or to step over water poured out", and in Hullin 105b it states "Drink not froth, for it gives cold in the head; nor blow it away, for that gives headache; nor get rid of it otherwise, for that brings poverty; but wait until it subsides".The Evil eye features prominently in rabbinic writings, one of which teaching saying, "ninety-nine die from the effects of the evil eye, while one dies by the hand of heaven." The wearing of amulets containing the names of angels charged with healing and invocations of various sorts was often thought to be a prophylactic against certain illnesses and the Evil eye. The practice is mentioned in the Mishnah, and in the book, Alpha Beta la-Ben Sira.
