The greatest wrath of God on Israel was incurred during the reign of king

Explanation

The reign of King Ahab is often associated with significant disobedience and idolatry in Israel which led to God's displeasure and wrath. The prophet Elijah confronted Ahab and his wife Jezebel for their promotion of Baal worship and other sinful practices. A specific incident illustrating God's wrath during Ahab's reign is the confrontation on Mount Carmel, where Elijah challenged the prophets of Baal (1 Kings 18). Ahab's reign is often considered a period of great apostasy in Israel's history.
