Melachim Alef 16:22-24

Orthodox Jewish Bible

²² But the people that followed Omri were stronger against the people that followed Tivni Ben Ginat; so Tivni died, and Omri reigned as Melech.

²³ In the thirty and first year of Asa Melech Yehudah began Omri to reign as Melech over Yisroel, reigning twelve years; shesh shanim reigned he in Tirtzah.

²⁴ And he bought the Har Shomron from Shemer for two talents of kesef, and built on the hill, and called the shem of the Ir which he built, after the shem of Shemer, adonei hahar (owner of the hill), Shomron.
