John Gill Commentary 1 Kings 16:28

"So Omri slept with his fathers, and was buried in Samaria; and Ahab his son reigned in his stead." — 1 Kings 16:28 (ASV)

So Omri slept with his fathers
Died a natural death:

and was buried in Samaria ;
the city he had built, and now the royal seat and metropolis of the kingdom:

and Ahab his son reigned in his stead ;
of whom much is said in the following history.
