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."
