Deuteronomy 18:9-11

9When you go into the land that the Lord your God is giving you, be careful! Do not learn to do the evil things that the nations who live there are doing.

10Nobody among you must ever burn your child in a fire, as an offering. Nobody must use magic or other things to learn about future times. There must not be any magicians or diviners.

11Never use magic to curse anyone. Never try to speak to the spirits of dead people or other spirits.
