Leviticus 18:7-9

International Children’s Bible

⁷ “‘You must not shame your father by having physical relations with your mother. She is your mother. Do not have physical relations with her. ⁸ You must not have physical relations with your father’s wife. That would shame your father.

⁹ “‘You must not have physical relations with your sister. She may be the daughter of your father or your mother. It doesn’t matter if she was born in your house or somewhere else.
