פירוש על ברכות 105:31

In 'Erubin 64 b, the Rabbis deplore that the Jewish women are addicted to sorcery. Hillel declared : "The more women, the more witchcraft"; Abot ii. 8 ; Singer, p. 188. Roman writers also refer to this fact ; cf. Radin, Jews among the Greeks atid Romans, p. 325. For the Talmudic references, see Blau, Das altjudische Zauberwesen, pp. 28 ff.
