Harmless fun?

"There shall not be found among you anyone who makes his son or his daughter pass through the fire, one who uses divination, one who practices witchcraft, or one who interprets omens, or a sorcerer, or one who casts a spell, or a medium, or a spiritist, or one who calls up the dead. For whoever does these things is detestable to the LORD; and because of these detestable things the LORD your God will drive them out before you. You shall be blameless before the LORD your God. For those nations, which you shall dispossess, listen to those who practice witchcraft and to diviners, but as for you, the LORD your God has not allowed you to do so."

-- Deuteronomy 18:10-14
