7Do not have sex with your mother. That would cause your father to be ashamed.

8Do not have sex with any wife of your father. Your father would be ashamed.

9Do not have sex with your sister. Do not have sex with a sister who is your mother's daughter or your father's daughter. It does not matter if she was born in your house or in another house. Do not have sex with any sister.

10Do not have sex with any granddaughter. That would make you ashamed.

11Do not have sex with the daughter of your father and his wife. She is your sister.

12Do not have sex with your father's sister. She is his near relative.

13Do not have sex with your mother's sister. She is her near relative.

14Do not have sex with the wife of your father's brother. That would make your uncle ashamed. His wife is your aunt.

15Do not have sex with your son's wife.

16Do not have sex with your brother's wife. That would make your brother ashamed.

17Do not have sex with both a woman and her daughter. Do not have sex with her son's daughter or with her daughter's daughter. They are her near relatives. It would be an evil thing to do.

18Do not marry your wife's sister as a second wife. If your wife is still alive, do not have sex with her sister.
