I have been trying to understand better the religious attitude of King Ahab. He was famously denounced by the usurper King Jehu, who, in the generation after Ahab, massacred his 60 sons along with his queen (Jezebel). In 2 Kings 10:18, Jehu facetiously declared "Ahab served Ba′al a little; but Jehu will serve him much" just prior to putting hundreds of Ba'al worshipers (or "servants") to death when he destroyed the Temple of Ba'al in Samaria.
Other examples of Ahab's association with Ba'al include the prophet Elijah saying, when Ahab called him a "troubler of Israel":
“I have not troubled Israel; but you have, and your father’s house, because you have forsaken the commandments of the Lord and followed the Ba′als. (1 Kings 18:18)
In addition the narrator of the Books of Kings says:
Manas′seh... rebuilt the high places which Hezeki′ah his father had destroyed; and he erected altars for Ba′al, and made an Ashe′rah, as Ahab king of Israel had done, and worshiped all the host of heaven, and served them. (2 Kings 21:3)
My problem is that I cannot find definite examples of Ahab actually worshiping Ba'al. His wife Jezebel clearly did so. But Ahab is shown elsewhere to be a believer in the Lord, who sometimes supported him as King of Israel. In 1 Kings 20 when Ahab faced war against Ben-Hadad of Syria:
A prophet came near to Ahab king of Israel and said, "Thus says the Lord, 'Have you seen all this great multitude? Behold, I will give it into your hand this day; and you shall know that I am the Lord.'" (20:28)
Prophets of God continued to support Ahab in this campaign until Ben-Hadad was defeated, but others soon opposed him. Then in 1 Kings 22, we read:
Then the king of Israel (Ahab) gathered the prophets together, about four hundred men, and said to them, “Shall I go to battle against Ramoth-gilead, or shall I forbear?” And they said, “Go up; for the Lord will give it into the hand of the king.” But Jehosh′aphat said, “Is there not here another prophet of the Lord of whom we may inquire?” (6-7)
Here it seems that Ahab seeks advice from 400 prophets of the Lord, not Ba'al, and that Jehoshaphat too considers them to be prophets of the Lord, although not necessarily accurate in their advice. On the other hand, the context of the event is that the Lord has put a "lying spirit" into the mouths of these prophets in order to give Ahab bad advice.
When the narrator summarizes Ahab's sins, he says:
Ahab the son of Omri did evil in the sight of the Lord more than all that were before him. And as if it had been a light thing for him to walk in the sins of Jerobo′am the son of Nebat, he took for wife Jez′ebel the daughter of Ethba′al king of the Sido′nians, and went and served Ba′al, and worshiped him. He erected an altar for Ba′al in the house of Ba′al, which he built in Samar′ia. And Ahab made an Ashe′rah. Ahab did more to provoke the Lord, the God of Israel, to anger than all the kings of Israel who were before him. (1 Kings 16:31-32)
So it seems the Bible portrays Ahab in two ways in relation to Ba'al: as the par-excellence example of a Ba'al worshiper, but also as a believer in the Lord who sought the Lord's advice but grievously erred by tolerating and even encouraging Ba'al worship.
My question is: how ardent was Ahab in his support of Ba'al? Are then any examples of his actually worshiping Ba'al, or was his sin more like Solomon's, materially supporting his wife's religion by building a Temple for her, but not being a believer in this religion himself?
