1 Kings 16:15-17

The people were encamped against Gibbethon Which had been besieged many years before, but, it seems, was then relieved or afterward recovered by the Philistines, while the Israelites were in a distracted condition through civil broils and contentions. It was, however, now again invested. The people heard say, Zimri has conspired, &c. Notice was soon brought to the camp that Zimri had slain their king, and set up himself in Tirzah, the royal city; whereupon they chose Omri king in the camp, that they might, without delay, avenge the death of Elah upon Zimri. Thus proud aspiring men ruin one another, and involve others in ruin. Omri went up from Gibbethon The siege of which was instantly quitted. And all Israel with him All the army that were at the siege.
