Devarim 18:10-11

There shall not be found among you any one that maketh his ben or his bat to pass through the eish or kosem kesamim (a diviner of divination) or a m'onen (soothsayer, astrologer), or a m'nachesh (one who interprets omens), or a mekhashshef (witch). Or one who casts spells, or one who inquires of a ghost or a familiar spirit, or a doresh el hamesim (a consulter of the dead ones, i.e., a necromancer).
