Baasha smote him at Gibbethon, which belonged to the Philistines This was a city in the tribe of Dan, given to the Levites, (Joshua 19:44; Joshua 21:23,) who quitted it, as they did the rest of their cities, when Jeroboam would not suffer them to execute their office, 2 Chronicles 11:14; and the Philistines, it is likely, seized upon it, being adjoining to their country. But it appears, Nadab was now endeavouring to recover it out of their hands, as of right belonging to him; and here, in the midst of his army, did Baasha, with others, conspire against him, and kill him: and so little interest had he in the affections of his people, that his army not only did not avenge his death, but chose his murderer his successor. Whether Baasha did this upon a personal pique against Nadab, or to be revenged on the house of Jeroboam for some affront received from them; or whether under pretence of freeing his country from the tyranny of an ill prince; or whether purely from a principle of ambition, to make way for himself to the throne, doth not appear; but having slain him, he reigned in his stead.
