1 Kings 18:29

They prophesied. These agents of Baal were called prophets (v. 19). The performance of their service as a whole may have been considered an act of prophesying. Or probably in a more restricted sense they prophesied as did Saul, who “prophesied in the midst of the house” when an evil spirit came upon him (1 Sam. 18:10). Saul’s experience may have been like that of devil worshipers in Oriental lands today, who are said sometimes to work themselves up to a high state of religious frenzy, when they give utterance to unintelligible noises and grunts. Satan and his angels were present at Carmel and would have done anything within their power to bring down the desired fire had this been permitted by God. But the Lord, although allowing the demons to exhibit some of the more revolting aspects of their presence in men, did not allow Satan to bring down fire in the name of Baal.
