1 Kings 16:24-26

24Then he bought the hill of Samaria from Shemer for two talents of silver, and built a city on the hill. He named the city that he built Samaria, based on the name Shemer, the owner of the hill.

25But Omri did what was evil in Adonai’s eyes, and acted more wickedly than all who were before him.

26For he walked in all the ways of Jeroboam son of Nebat and in the sins that he had caused Israel to commit, vexing Adonai God of Israel, with their useless idols.
