A height, a city of the Philistines in the territory of Dan, given to the Kohathites (Josh. 19:44; 21:23). Nadab the king of Israel, while besieging it, was slain under its walls by Baasha, one of his own officers (1 Kings 15:27). It was in the possession of the Philistines after the secession of the ten tribes (2 Chr. 11:13, 14).
Gibbethon
Gibbethon was a Philistine town that Israel’s kings kept coming back to, and twice its siege coincided with a change of king. Nadab and all Israel were besieging it when Baasha conspired against Nadab and “smote him at Gibbethon, which belonged to the Philistines.” In the next generation, Zimri reigned just seven days in Tirzah while the people were encamped against Gibbethon again. Then “Omri went up from Gibbethon, and all Israel with him, and they besieged Tirzah.” First Kings 15 and 16 move quickly through all of this, so they read well in one sitting.
