Leviticus 18:16-18

New Century Version

¹⁶ “‘You must not have sexual relations with your brother’s wife. That would shame your brother.

¹⁷ “‘You must not have sexual relations with both a woman and her daughter. And do not have sexual relations with this woman’s granddaughter, either the daughter of her son or her daughter; they are her close relatives. It is evil to do this.

¹⁸ “‘While your wife is still living, you must not take her sister as another wife. Do not have sexual relations with her.
