1 Kings 16:23 - Ellicott's Commentary On The Whole Bible

Began Omri to reign over Israel. — The accession of Omri after this long civil war opened a new epoch of more settled government and prosperity for about forty-eight years. Omri had (as appears from 1 Kings 20:34) to purchase peace with Syria by some acknowledgment of sovereignty and cession of cities. He then allied himself with the royal house of Tyre, probably both for strength against Syria, and for revival of the commercial prosperity of the days of Solomon, and proceeded to found a new capital in a strong position. That he was a warrior is indicated by the phrase, “the might that he shewed.” Probably, like Jeroboam and Baasha, he also had his opportunity of restoring the spiritual strength of his people by returning to the pure worship of God, and threw it away, doing “worse than all who were before him.”
