Leviticus 18:14-16

Complete Jewish Bible

¹⁴ You are not to disgrace your father’s brother by having sexual relations with his wife, because she is your aunt. 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.
