LEV234 One shall not uncover the nakedness of one's father's wife, despite that she is not one's mother. As explained in [See [[LEV233]] Leviticus 18:7 nakedness CHINUCH 131], regarding forbidden relations with close relatives. In addition, in this instance, the son shames and disgraces his father, whom the son is obligated to honor. Benefits of honoring one's father have already been noted (See [[EXOD421]] Exodus 20:12 honor CHINUCH 26-7).
