1 Kings 16:23-24 RSV

23 In the thirty-first year of Asa king of Judah, Omri began to reign over Israel, and reigned for twelve years; six years he reigned in Tirzah.
24 He bought the hill of Sama'ria from Shemer for two talents of silver; and he fortified the hill, and called the name of the city which he built, Sama'ria, after the name of Shemer, the owner of the hill.
