Leviticus 20:19-21

Modern English Version

¹⁹ You shall not have relations with your mother’s sister or your father’s sister, for this is to expose the nakedness of one’s relative. They shall bear their iniquity.

²⁰ If a man lies with his uncle’s wife, he has exposed his uncle’s nakedness. They shall bear their sin. They shall die childless.

²¹ If a man lies with his brother’s wife, it is impurity. He has exposed his brother’s nakedness. They shall be childless.
