18 Thou shalt not suffer a witch to live.
Witchcraft is simply using manipulation of any kind to get what you want. A woman who uses her sexual wiles to manipulate a man to do something he knows is not right or doesn't initially want to do is using witchcraft. It doesn't stop there...bribery is witchcraft. It does the same thing. Placing objects in strategic places to make someone question the motives or loyalty of someone is using manipulative tactics - witchcraft. There is more, but I think you get the picture.
In other words, doing anything to make something happen outside of it's natural course is witchcraft.
Anyone suffering from a sins such as envy or anger is subject to be tempted to use witchcraft. This is why God teaches us to be in control of our emotions such as anger and resentment, and to be content with what He gives us.
