Leviticus 20:17-19

New International Reader's Version

¹⁷ “ ‘Suppose a man gets married to his sister and has sex with her. That is a shameful thing to do. It does not matter whether she is the daughter of his father or of his mother. They must be separated from their community in front of everyone. That man has brought shame on his sister. He will be responsible for what he has done.

¹⁸ “ ‘Suppose a man has sex with a woman during her monthly period. He has uncovered the place where her bleeding was coming from. And she has let him do it. So both of them must be separated from their people.

¹⁹ “ ‘Do not have sex with the sister of either your mother or your father. That would bring shame on a close relative. Both of you would be held responsible for what you have done.
