1 Kings 16:21-26

21At that time the people of Israel were divided: half the people followed Tibni son of Ginath, to make him king, and half followed Omri.

22However, the people who followed Omri proved stronger than those who followed Tibni son of Ginath. So Tibni died and Omri became king.

23In the thirty-first year of Judah’s King Asa, Omri became king over Israel, and he reigned twelve years. He reigned six years in Tirzah,

24then he bought the hill of Samaria from Shemer for 150 pounds of silver, and he built up the hill. He named the city he built Samaria based on the name Shemer, the owner of the hill.

25Omri did what was evil in the Lord’s sight; he did more evil than all who were before him.

26He walked in all the ways of Jeroboam son of Nebat in every respect and continued in his sins that he caused Israel to commit, angering the Lord God of Israel with their worthless idols.
