Mishneh Torah, Foreign Worship and Customs of the Nations
He who practices enchantry or spiritualism of his own free will, wantonly, is guilty of a sin punishable by excision; if there be witnesses, and he received due warning, he is stoned. If he erred, he should offer a standard sin-offering. How is enchantry practiced? One stands and burns a kind of incense known to such practicioners, holding in his hand a myrtle-branch which he waves, the while uttering in a murmur words known to such practicioners, so that the supplicant thinks that he hears one conversing with him and answering his questions in words that appear to be coming from beneath the earth uttered in a very low voice, which is scarcely audible to the ear but rather perceptible to the mind. Or, one who holds a skull of a deceased person, and burns incense to it, and divines by it, so that it becomes evident as if an extremely low ventriloquous voice makes reply. All such are practices of enchantry, and whosoever practices one such, is stoned.2Sanhedrin, 65a–b. C.
