John Gill Commentary 1 Kings 16:32

"And he reared up an altar for Baal in the house of Baal, which he had built in Samaria." — 1 Kings 16:32 (ASV)

And he reared up an altar for Baal in the house of Baal,
which he had built in Samaria .
] That he might not go so far as Tyre or Zidon; and for his wife's convenience also he built a temple in Samaria for Baal, and erected an altar there to offer sacrifices upon it unto him; so open and daring was he in his idolatrous practices.
