Leviticus 20:19-27

19 “Do not have sexual relations with your aunt, whether your mother’s sister or your father’s sister. This would dishonor a close relative. Both parties are guilty and will be punished for their sin.
20 “If a man has sex with his uncle’s wife, he has violated his uncle. Both the man and woman will be punished for their sin, and they will die childless.
21 “If a man marries his brother’s wife, it is an act of impurity. He has violated his brother, and the guilty couple will remain childless.
22 “You must keep all my decrees and regulations by putting them into practice; otherwise the land to which I am bringing you as your new home will vomit you out.
23 Do not live according to the customs of the people I am driving out before you. It is because they do these shameful things that I detest them.
24 But I have promised you, ‘You will possess their land because I will give it to you as your possession—a land flowing with milk and honey.’ I am the LORD your God, who has set you apart from all other people.
25 “You must therefore make a distinction between ceremonially clean and unclean animals, and between clean and unclean birds. You must not defile yourselves by eating any unclean animal or bird or creature that scurries along the ground. I have identified them as being unclean for you.
26 You must be holy because I, the LORD, am holy. I have set you apart from all other people to be my very own.
27 “Men and women among you who act as mediums or who consult the spirits of the dead must be put to death by stoning. They are guilty of a capital offense.”
