Well you got that right, Juk. Stay away from it. Beware of the dark side, Juk. It's real and people get seduced by it.
Familiar : 2. A demon or evil spirit supposed to attend at a call. But in general we say, a familiar spirit. Webster's 1828
Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the LORD your God. Leviticus 19:31
There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer. For all that do these things are an abomination unto the LORD: and because of these abominations the LORD thy God doth drive them out from before thee. Thou shalt be perfect with the LORD thy God. Deuteronomy 18:10-13
And ye shall be holy unto me: for I the LORD am holy, and have severed you from other people, that ye should be mine. A man also or woman that hath a familiar spirit, or that is a wizard, shall surely be put to death: they shall stone them with stones: their blood shall be upon them. Leviticus 20:26-27
