(17) You shall not tolerate a sorceress.

The mishna teaches that the case of the warlock is referring to one who performs a real act of sorcery. The Sages taught in a baraita: The verse: “You shall not allow a witch to live” (Exodus 22:17), does not refer only to a female who practices sorcery; both a man and a woman are included. If so, why does verse state “a witch”? This is because most women are familiar with witchcraft.

(31) Do not turn to ghosts and do not inquire of familiar spirits, to be defiled by them: I יהוה am your God.

§ The Sages taught: A necromancer [ov] is one who causes the voice of the dead to be heard speaking from between his joints or from his armpit. A sorcerer [yideoni] is one who places a bone of an animal called a yadua in his mouth, and the bone speaks on its own.

(26) You shall not eat anything with its blood. You shall not practice divination or soothsaying.

§ The Sages taught: What is the definition of the soothsayer mentioned in the verse: “There shall not be found among you…a soothsayer” (Deuteronomy 18:10)? Rabbi Shimon says: This is one who applies seven types of semen [zekhur] to one’s eye in order to perform sorcery. And the Rabbis say: This is one who deceives the eyes, as though he is performing sorcery. Rabbi Akiva says: This is one who calculates the fortune of times and hours, and says, for example: Today is a propitious day for going away on a journey; tomorrow is propitious for purchasing property successfully. Or he says that on the eve of the Sabbatical Years, the wheat harvest is generally good; uprooting legumes rather than cutting them from above the ground prevents them from going bad.

Abaye said, The laws of sorcery are like the laws of work on Shabbat, in that, some actions get you stoned, some actions are exempt from punishment but forbidden, and some are allowed ab initio. The one who performs sorcery is stoned. The one who makes illusions is exempt from stoning but still did wrong. Things that are allowed are like the actions of Rav Chanina and Rav Oshaya, who would learn the laws of creation every Friday night and a young calf would be created for them and they would eat it.

What did [Honi HaMe'aggel] do? He drew a circle on the ground and stood inside it and said before God: Master of the Universe, Your children have turned their faces toward me, as I am like a member of Your household. Therefore, I take an oath by Your great name that I will not move from here until You have mercy upon Your children and answer their prayers for rain. Rain began to trickle down, but only in small droplets. He said: I did not ask for this, but for rain to fill the cisterns, ditches, and caves with enough water to last the entire year. Rain began to fall furiously. He said: I did not ask for this damaging rain either, but for rain of benevolence, blessing, and generosity.

Rava said: A person is obligated to become intoxicated with wine on Purim until he is so intoxicated that he does not know how to distinguish between cursed is Haman and blessed is Mordecai. The Gemara relates that Rabba and Rabbi Zeira prepared a Purim feast with each other, and they became intoxicated to the point that Rabba arose and slaughtered Rabbi Zeira. The next day, when he became sober and realized what he had done, Rabba asked God for mercy, and revived him. The next year, Rabba said to Rabbi Zeira: Let the Master come and let us prepare the Purim feast with each other. He said to him: Miracles do not happen each and every hour, and I do not want to undergo that experience again.
