C. F. Keil and Franz Delitzsch on 1 Kings 18:40-46

1Ki 18:40-46

Elijah availed himself of this enthusiasm of the people for the Lord, to deal a fatal blow at the prophets of Baal, who turned away the people from the living God. He commanded the people to seize them, and had them slain at the brook Kishon, and that not so much from revenge, i.e., because it was at their instigation that queen Jezebel had murdered the prophets of the true God (1Ki 18:13), as to carry out the fundamental law of the Old Testament kingdom of God, which prohibited idolatry on pain of death, and commanded that false prophets should be destroyed (Deu 17:2-3; Deu 13:13.).It was necessary that idolatry and temptation to the worship of idols should be punished with death, as a practical denial of Jehovah the true God and Lord of His chosen people, if the object of the divine institutions was to be secured. By putting the priests of Baal to death, therefore, Elijah only did what the law required; and inasmuch as the ordinary administrators of justice did not fulfil their obligations, he did this as an extraordinary messenger of God, whom the Lord had accredited as His prophet before all the people by the miraculous answer given to his prayer. - To infer from this act of Elijah the right to institute a bloody persecution of heretics, would not only indicate a complete oversight of the difference between heathen idolaters and Christian heretics, but the same reprehensible confounding of the evangelical standpoint of the New Testament with the legal standpoint of the Old, which Christ condemned in His own disciples in Luk 9:55-56.
