Then the people of Israel were divided into two parts; half of the people followed Tibni son of Ginath, to make him king, and half followed Omri. But the people who followed Omri overcame the people who followed Tibni son of Ginath; so Tibni died, and Omri became king. In the thirty-first year of King Asa of Judah, Omri began to reign over Israel; he reigned for twelve years, six of them in Tirzah.
Samaria the New Capital
He bought the hill of Samaria from Shemer for two talents of silver; he fortified the hill, and called the city that he built, Samaria, after the name of Shemer, the owner of the hill.
Omri did what was evil in the sight of the Lord; he did more evil than all who were before him. For he walked in all the way of Jeroboam son of Nebat, and in the sins that he caused Israel to commit, provoking the Lord, the God of Israel, to anger by their idols. Now the rest of the acts of Omri that he did, and the power that he showed, are they not written in the Book of the Annals of the Kings of Israel? Omri slept with his ancestors, and was buried in Samaria; his son Ahab succeeded him.
