1 Kings 16:24-26

24Omri bought the hill Samaria from Shemer for two talents of silver, and he built a city on the hill [and fortified it], and named the city which he built Samaria, after the owner of the hill, Shemer.

25But Omri did evil in the sight of the Lord, and acted more wickedly than all who came before him.

26He walked in all the ways of Jeroboam the son of Nebat and in his sin, which he made Israel commit, provoking the Lord God of Israel, [to anger] with their idols.
