Conversion to Judaism requires a period of study under a Rabbi. An ancient Jewish tradition is for the Rabbi to turn away prospective converts three times, to test the convert's dedication to Judaism and sincerity in desiring to convert. Many Rabbis, especially in non-Orthodox Jewish sects, do not do this in the modern age. | Conversion to Judaism requires a period of study under a Rabbi.
