Yeah, the irony of that is impressive...
1 Kings 18:36-40
At the customary time for offering the evening sacrifice, Elijah walked up to the altar and prayed, “O Lord God of Abraham, Isaac, and Israel, prove today that you are the God of Israel and that I am your servant; prove that I have done all this at your command. 37 O Lord, answer me! Answer me so these people will know that you are God and that you have brought them back to yourself.”
38 Then, suddenly, fire flashed down from heaven and burned up the young bull, the wood, the stones, the dust, and even evaporated all the water in the ditch!
39 And when the people saw it, they fell to their faces upon the ground shouting, “Jehovah is God! Jehovah is God!”
40 Then Elijah told them to grab the prophets of Baal. “Don’t let a single one escape,” he commanded.
So they seized them all, and Elijah took them to Kishon Brook and killed them there.
