¹³ You must not have sexual relations with your mother’s sister; she is your mother’s close relative. ¹⁴ You must not have sexual relations with the wife of your father’s brother, because this would shame him. She is your aunt.

¹⁵ “‘You must not have sexual relations with your daughter-in-law; she is your son’s wife. Do not have sexual relations with her.
