1 Kings 16:22-24

New Century Version

²² Omri’s followers were stronger than the followers of Tibni son of Ginath, so Tibni died, and Omri became king.

²³ Omri became king of Israel during the thirty-first year Asa was king of Judah. Omri ruled Israel for twelve years, six of those years in the city of Tirzah. ²⁴ He bought the hill of Samaria from Shemer for about one hundred fifty pounds of silver. Omri built a city on that hill and called it Samaria after the name of its earlier owner, Shemer.
