1 Kings 16:24-26

24And he bought the hill Samaria of Shemer for two talents of silver, and built on the hill, and called the name of the city which he built, after the name of Shemer, owner of the hill, Samaria.1

25But Omri wrought evil in the eyes of Yhwh, and did worse than all that were before him. 26For he walked in all the way of Jeroboam the son of Nebat, and in his sin wherewith he made Israel to sin, to provoke Yhwh God of Israel to anger with their vanities.
