1 Kings 16:21-27

Then the people of Israel were divided in half. Half of the people followed Tibni the son of Ginath, to make him king, and the other half followed Omri. But the people who followed Omri prevailed over the people who followed Tibni the son of Ginath. So Tibni died and Omri became king. In the thirty-first year of Asa king of Judah, Omri became king over Israel and reigned for twelve years. He reigned six years at Tirzah. Omri bought the hill Samaria from Shemer for two talents of silver, and he built a city on the hill [and fortified it], and named the city which he built Samaria, after the owner of the hill, Shemer. But Omri did evil in the sight of the LORD, and acted more wickedly than all who came before him. He walked in all the ways of Jeroboam the son of Nebat and in his sin, which he made Israel commit, provoking the LORD God of Israel, [to anger] with their idols. Now as for the rest of the acts of Omri which he did, and his might which he showed, are they not written in the Book of the Chronicles of the Kings of Israel?
