Ahab
One of Ahab's most famous enemies is an old prophet (a man of God) named Elijah. He continually rebukes Ahab for being so disobeying to the Lord, and when Ahab summoned all the prophets of Baal against Elijah at Mount Carmel, and set two altars for them, Elijah won by calling on God and letting fire come and burn the sacrifice, and the prophets of Baal were immediately killed by the Israelites. Importantly, even here Ahab does nothing, either to stop or help Elijah.
