(16) Made Omri . . . king.--This exaltation of Omri, as a matter of course, shows how entirely the kingdom of Israel had become the prize of the sword. By a curious coincidence (see 1Kings 15:27) the dynasty of Baasha had been founded in the camp before the same city of Gibbethon. Zimri's conspiracy appears to have been hastily planned, with no provision of adequate means of support; for Tirzah is taken at once.

Pulpit Commentary

Verse 16. - And the people that were encamped heard say, Zimri hath conspired, and hath also slain the king: wherefore all Israel [obviously, all the army. Cf. 1 Kings 12:1, 16, 18] made Omri, the captain of the host, king over Israel that day in the camp. It was hardly likely they would submit to the usurpation of Zimri. Not only had he occupied a subordinate position, but his murder of all Elah's friends must have made him a host of enemies in the camp. It was the natural thing for them, therefore, to turn to Omri. He had the advantage of being in possession. The captain of the host stood next to the king (2 Kings 4:13; 2 Samuel 5:8; 2 Samuel 19:13; 2 Samuel 20:23), and twice stepped into his place (2 Kings 9:5). This history has many parallels in that of the Roman empire.]

Matthew Henry's Concise Commentary

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.

Gill's Exposition of the Entire Bible

And the people that were encamped heard say, Zimri hath conspired, and hath also slain the king,.... Tidings came to the army of what he had done, which was displeasing to them:

wherefore all Israel made Omri, the captain of the host, king over Israel that day in the camp; that is, all Israel that were in the army proclaimed Omri, their general, king; just as the Roman army declared Vespasian, their general, emperor of Rome, and as several of the emperors were chosen.
