Matthew Henry on 1 Kings 16:15-28
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.

John Gill on 1 Kings 16:19
For his sins which he sinned in doing evil in the sight of the Lord,.... In the former part of his life, as well as now:
