Leviticus 18:7-9

New International Reader's Version

⁷ “ ‘Do not bring shame on your father by having sex with your mother. Do not have sex with her. She is your mother.

⁸ “ ‘Do not have sex with any other wife of your father. That would bring shame on your father.

⁹ “ ‘Do not have sex with your sister. It does not matter whether she is your father’s daughter or your mother’s daughter. It does not matter whether she was born in the same home as you were or somewhere else.
