EXOD634 Do not allow a sorceress to live. Sorcery (witchcraft) is a known evil that leads to many types of pitfalls and social ills. Accordingly, Hashem commands us to rid the world of all practitioners of sorcery. In His eyes, sorcery is an unwanted element in the world, for He wants the world to function according to the natural order that He instituted at the time of Creation. Those who practice sorcery seek to change the natural order.
