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.

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.Their vanities - The "calves." The Hebrews call an idol by terms signifying "emptiness," "vapor," or "nothingness." (Compare marginal references.) 15-18. did Zimri reign seven days—The news of his conspiracy soon spread, and the army having proclaimed their general, Omri, king, that officer immediately raised the siege at Gibbethon and marched directly against the capital in which the usurper had established himself. Zimri soon saw that he was not in circumstances to hold out against all the forces of the kingdom; so, shutting himself up in the palace, he set it on fire, and, like Sardanapalus, chose to perish himself and reduce all to ruin, rather than that the palace and royal treasures should fall into the hands of his successful rival. The seven days' reign may refer either to the brief duration of his royal authority, or the period in which he enjoyed unmolested tranquillity in the palace. Which had been besieged before, 1 Kings 15:27, but, it seems, was then relieved, or afterwards recovered by the Philistines, taking the advantage of the disorders and contentions which were among their enemies.

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.

In the twenty and seventh year of Asa king of Judah did Zimri reign seven days in Tirzah. And the people were encamped {g} against Gibbethon, which belonged to the Philistines.
