Leviticus 18:16-18

EasyEnglish Bible

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

¹⁷ Do 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.

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