1. Könige 16:15

The Reign of Zimri lasted only seven days. As soon as the people of war (העם), who were besieging Gibbethon (see at Kg1 15:27), heard of his conspiracy, his usurpation of the throne, and his murderous deeds, they proclaimed Omri king in the camp of the military commanders, and he at once, with all Israel, i.e., all the army, raised the siege of Gibbethon, to lay siege to Thirza. Now when Zimri saw that the city was taken, he went into the castle of the royal palace and burned the king's house over his own head, as Sardanapalus did, according to Justin (Hist. i. 3). ארמון does not mean harem (Ewald), but the high castle (from ארם, to be high); here and in Kg2 15:25, the citadel of the royal palace, which consisted of several buildings.

Solomon observes (Pro 28:2) that for the transgression of a land many were the princes thereof (so it was here in Israel), but by a man of understanding the state thereof shall be prolonged - so it was with Judah at the same time under Asa. When men forsake God they are out of the way of rest and establishment. Zimri, and Tibni, and Omri, are here striving for the crown. Proud aspiring men ruin one another, and involve others in the ruin. These confusions end in the settlement of Omri; we must therefore take him along with us through this part of the story. I. How he was chosen, as the Roman emperors often were, by the army in the field, now encamped before Gibbethon. Notice was soon brought thither that Zimri had slain their king (Kg1 16:16) 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. Though he was idle and intemperate, yet he was their king, and they would not tamely submit to his murderer, nor let the treason go unpunished. They did not attempt to avenge the death of Nadab upon Baasha, perhaps because the house of Baasha had ruled with more gentleness than the house of Jeroboam; but Zimri shall feel the resentments of the provoked army. The siege of Gibbethon is quitted (Philistines are sure to gain when Israelites quarrel) and Zimri is prosecuted. II. How he conquered Zimri, who is said to have reigned seven days (Kg1 16:15), so long before Omri was proclaimed king and himself proclaimed traitor; but we may suppose it was a longer time before he died, for he continued long enough to show his inclination to the way of Jeroboam, and to make himself obnoxious to the justice of God by supporting his idolatry, Kg1 16:19. Tirzah was a beautiful city, but not fo…

16:15-17 Although Zimri commanded half of the royal chariots (16:9), he was in Tirzah rather than with the army . . . attacking . . . Gibbethon. He apparently did not have the respect of the armed forces; they saw his acts as treason and chose their commander Omri as the new king of Israel.
