Verse 15. - In the twenty and seventh year of Asa king of Judah did Zimri reign [The same word elsewhere translated in A.V. began to reign. It is really an aorist = succeeded to the throne] seven days in Tirzah. And the people were encamped [Heb. encamping] against Gibbethon, which belonged to the Phistines. [It has at first sight a suspicious look that two kings of Israel, within an interval of about twenty-five years, should have been slain by conspirators during a siege of this place. But when the narrative is examined, its probability and consistency become at once apparent. Stanley assumes that the siege lasted over the whole of this period, but it is more likely that when Baasha found himself king, he discovered that he had domestic matters enough upon his hands, without a foreign war, and so he raised the siege. It is very probable that he feared opposition such as Zimri and Omri subsequently experienced. And his wars with Asa and with Syria may well have prevented his renewing the undertaking. On the accession of Elah, however, with the usual ambition and impetuosity of youth, it was decided to recommence the siege and to win this city back for Israel. But the fate of Nadab, and the consequent ill omen attaching to the place would not be forgotten, and this, as well as his voluptuous habits, may have deterred the faineant Elah from besieging it in person, while the conspiracy which marked the former siege may at the same time have suggested to Zimri and others the thought of conspiring against Elah.]

16:15-28 When men forsake God, they will be left to plague one another. Proud aspiring men ruin one another. Omri struggled with Tibni some years. Though we do not always understand the rules by which God governs nations and individuals in his providence, we may learn useful lessons from the history before us. When tyrants succeed each other, and massacres, conspiracies, and civil wars, we may be sure the Lord has a controversy with the people for their sins; they are loudly called to repent and reform. Omri made himself infamous by his wickedness. Many wicked men have been men of might and renown; have built cities, and their names are found in history; but they have no name in the book of life.In the twenty and seventh year of Asa king of Judah did Zimri reign seven days in Tirzah, &c. Until the army under Omri came and took the palace, and destroyed him:

and the people were encamped against Gibbethon, which belongeth to the Philistines; it was besieged in Nadab's time, but upon his death, by Baasha, the siege was raised; or however, if then taken, it was recovered by the Philistines, and now besieged again by the Israelites, see 1 Kings 15:27.
