Omri then Ahab

In the thirty-first year of Asa king of Judah,
Omri became king of Israel,
and he reigned twelve years,
six of them in Tirza.
He bought the hill of Samaria from Shemer
for two talents of silver
and built a city on the hill,
calling it Samaria, after Shemer,
the name of the former owner of the hill.

But Omri did evil in the eyes of the Lord
and sinned more than all those before him.

In the thirty-eighth year of Asa king of Judah,
Ahab son of Omri became king of Israel,
and he reigned in Samaria over Israel twenty-two years.
Ahab son of Omri did more evil in the eyes of the Lord
than any of those before him.
He not only considered it trivial
to commit the sins of Jeroboam son of Nebat,
but he also married Jezebel
daughter of Ethbaal king of the Sidonians,
and began to serve Baal and worship him.
He set up an altar for Baal in the temple of Baal
that he built in Samaria.
Ahab also made an Asherah pole
and did more to provoke the Lord, the God of Israel,
to anger than did all the kings of Israel before him.
