Sanhedrin, fol. 17, col. 1.
Rabbi Shimon said, "An enchanter is one who passeth the exudation of seven different sorts of male creatures over the eye." The sages say he is one who practices and palms off optical illusions. Rabbi Akiva says, "He is one who calculates times and hours, and says To-day is good to start on a journey, To-morrow will be a lucky day for selling, The year before the Sabbatical year is generally good for growing wheat, The pulling up of pease will preserve them from being spoiled." According to the Rabbis, "An enchanter is he who augurs ill when his bread drops from his mouth, or if he drops the stick that supports him from his hand, or if his son calls after him, or a crow caws in his hearing, or a deer crosses his path, or he sees a serpent at his right hand or a fox on his left, or if he says to the tax-gatherer, 'Do not begin with me the first in the morning'; or, 'It is the first of the month'; or, 'It is the exit of the Sabbath,' i.e., the commencement of a new week."
Ibid., fol. 65, col. 2.
"By the term witch," the Rabbis say, "we are to understand either male or female." "If so," it is asked, "why the term 'witch,' in Exod. xxii. 18, in the Hebrew verse 17, is in the feminine gender?" "Because," it is answered, "most women are witches."
Ibid., fol. 67, col. 1.
If the proud (in Israel) were to cease, the magicians would also cease; as it is written (Isa. i. 25), "I will purge away thy dross and take away all thy tin."
