"Do not allow a sorceress to live." (Exodus 22:17)
Throughout this week's parasha, we see various laws where the Torah commands us as Jewish society "Mot OuMat" or "shall surely be put to death." Oddly we see a change in the language when it comes to the law regarding a sorcerer or sorceress - "Do not allow a sorceress to live". Our Rabbis answer this question by saying that the danger that surrounds such individuals, is very serious.
These individuals try to attribute events to the time of week, or season. They believe in false superstitions, and teach them to other people.
The Torah tells us "Tamim Tehiyeh Im Hashem Elokecha" – we must be "whole" with Hashem. What does this mean? We must be direct our approach to Hashem, without believing that any of the "hocus-pocus" or "voodoo" actually influences the way things eventually turn out.
Our Rabbis say that the language by the sorcerer or sorceress is different in the verse, be we must ensure that such a person does not live, for his or her "living" will cause others to learn their misguided ways, and undermine the very fabric of our religion- our belief solely in Hashem.
