Should anyone turn to mediums and fortune-tellers and follow their wanton ways, I will turn against such a one and cut him off from his people. Sanctify yourselves, then, and be holy; for I, the LORD, your God, am holy. Be careful, therefore, to observe what I, the LORD, who make you holy, have prescribed.
"Anyone who curses his father or mother shall be put to death; since he has cursed his father or mother, he has forfeited his life. If a man commits adultery with his neighbor's wife, both the adulterer and the adulteress shall be put to death.
If a man disgraces his father by lying with his father's wife, both the man and his stepmother shall be put to death; they have forfeited their lives. If a man lies with his daughter-in-law, both of them shall be put to death; since they have committed an abhorrent deed, they have forfeited their lives.
If a man lies with a male as with a woman, both of them shall be put to death for their abominable deed; they have forfeited their lives. If a man marries a woman and her mother also, the man and the two women as well shall be burned to death for their shameful conduct, so that such shamefulness may not be found among you.
If a man has carnal relations with an animal, the man shall be put to death, and the animal shall be slain. If a woman goes up to any animal to mate with it, the woman and the animal shall be slain; let them both be put to death; their lives are forfeit. If a man consummates marriage with his sister or his half-sister, they shall be publicly cut off from their people for this shameful deed; the man shall pay the penalty of having had intercourse with his own sister.
If a man lies in sexual intercourse with a woman during her menstrual period, both of them shall be cut off from their people, because they have laid bare the flowing fountain of her blood. You shall not have intercourse with your mother's sister or your father's sister; whoever does so shall pay the penalty of incest.
If a man disgraces his uncle by having intercourse with his uncle's wife, the man and his aunt shall pay the penalty by dying childless. If a man marries his brother's wife and thus disgraces his brother, they shall be childless because of this incest.
"A man or a woman who acts as a medium or fortune-teller shall be put to death by stoning; they have no one but themselves to blame for their death."
Leviticus 20:6-21, 27
