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 .
This encounter ends with Elijah victorious over the official Baal prophets of Israel in a contest held for the sake of the Israelites and their king , Ahab . The contest ends when Elijah 's God consumes the offering which the Baal worshipers could not induce their god to touch , after which Elijah slaughters the Baal prophets ( 1 Kings 18:17 -40 ) .
