Omri did what was evil in the sight of YHVH, and did more evil than all who were before him.
1 Kings 16:25

Omri is one of the few Israelite kings recorded in foreign histories, being recognized in the annals of the Hittites as a great leader and economist. Yet God dismisses him as just another evildoer. His greatest crime? He trusted in horses, chariots, and gold rather than in YHVH.
