   As it is stated in verses 10; and 15, that Zimri began to reign
   in the 27th year of Asa; and as he reigned only seven days,
   and Omri immediately succeeded him, this could not be the
   31st, but in the 27th year of Asa.  Jarchi, from Sedar Olam,
   reconciles this, by stating that Tibni and Omri began to reign
   jointly in the 27th year of Asa; and that Tibni dying about
   five years afterwards, Omri began to reign alone in the 31st
   year of Asa.
