Complete Jewish Bible

¹⁵ You are not to have sexual relations with your daughter-in-law; because she is your son’s wife. Do not have sexual relations with her. ¹⁶ You are not to have sexual relations with your brother’s wife, because this is your brother’s prerogative.

¹⁷ “‘You are not to have sexual relations with both a woman and her daughter, nor are you to have sexual relations with her son’s daughter or her daughter’s daughter; they are close relatives of hers, and it would be shameful.
