1 Kings 16:21-27

Then the people of Israel were divided into two parts: half of the people followed Tibni the son of Ginath, to make him king; the other half followed Omri. But the people who followed Omri prevailed over the people who followed Tibni the son of Ginath. And Tibni died and Omri became king. In the thirty-first year of Asa king of Judah, Omri became king over Israel and reigned twelve years; he reigned six years at Tirzah. He bought the hill Samaria from Shemer for two talents of silver; and he built on the hill, and named the city which he built Samaria, after the name of Shemer, the owner of the hill. Omri did evil in the sight of the LORD, and acted more wickedly than all who were before him. For he walked in all the way of Jeroboam the son of Nebat and in his sins which he made Israel sin, provoking the LORD God of Israel with their idols. Now 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?
