לֹא־תְקַלֵּ֣ל חֵרֵ֔שׁ וְלִפְנֵ֣י עִוֵּ֔ר לֹ֥א תִתֵּ֖ן מִכְשֹׁ֑ל וְיָרֵ֥אתָ מֵּאֱלֹהֶ֖יךָ אֲנִ֥י יְהוָֽה׃
你不可咒詛耳聾的人，也不可把絆腳的東西放在盲人面前；你要敬畏你的上帝。我是永恆者。
Teshuvot Maharshal
A. When life is in danger or such probability exists, or in case a limb of the body is in danger, such consultation is permissible; for sorcerers at times help through genuine remedies. But when no danger is involved this practice is prohibited, because sorcery in general is based on nothing else but falsehoods, deceit, and delusions.
