There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, OR ONE WHO CALLS UP THE DEAD.

1 Samuel 15:22-23
Behold, TO OBEY IS BETTER THAN SACRIFICE, And to heed than the fat of rams. For REBELLION IS AS THE SIN OF WITCHCRAFT, AND STUBBORNNESS IS AS INIQUITY AND IDOLATRY. Because YOU HAVE rejected the word of the LORD, HE also has REJECTED YOU from being king.”
