1 Kings 16:15-25

15 In Asa's twenty-seventh year as Judah's king, Zimri ruled for seven days in Tirzah while the army was camped near the Philistine city of Gibbethon.
16 When the army heard that Zimri had plotted [against the king] and killed him, the Israelite troops in the camp made Omri, the commander of the army, king of Israel.
17 Omri and the Israelite troops with him left Gibbethon and attacked Tirzah.
18 When Zimri saw that the city had been captured, he went into the stronghold in the royal palace and burned down the palace over his own head. He died
19 because of the sins he had committed--the things the LORD considered evil. Zimri lived like Jeroboam and led Israel to sin.
20 Isn't everything else about Zimri and his plot written in the official records of the kings of Israel?
21 Then the army of Israel was divided into two factions. Half of the army followed Tibni, son of Ginath, and wanted to make him king. The [other] half followed Omri.
22 But the half which followed Omri was stronger than the half which followed Tibni, Ginath's son. Tibni died, and Omri became king.
23 Omri began to rule Israel in Asa's thirty-first year as king of Judah. He ruled for 12 years, 6 of them in Tirzah.
24 Omri bought a hill from Shemer for 150 pounds of silver. He fortified the hill and built the city of Samaria on it. He named the city after its former owner, Shemer.
25 Omri did what the LORD considered evil. He did more evil things than all [the kings] before him.
