Then the fire of the Lord fell, and consumed the holocaust, and the wood, and the stones, and the dust, and licked up the water that was in the trench.

“In the time of Elijah, also, fire came down when he challenged the prophets of the heathen to light up the altar without fire. When they could not do so, he poured water three times over his victim, so that the water ran around about the altar; then he cried out, and the fire fell from the Lord from heaven and consumed the burnt offering. You are that victim. Contemplate in silence each single point. The breath of the Holy Spirit descends on you; he seems to burn you when he consumes your sins. The sacrifice that was consumed in the time of Moses was a sacrifice for sin, wherefore Moses said, as is written in the book of the Maccabees: "Because the sacrifice for sin was not to be eaten, it was consumed." Does it not seem to be consumed for you when in the sacrament of baptism the whole outer person perishes? "Our old self is crucified," the apostle exclaims. Herein, as the example of the Fathers teaches us, the Egyptian is swallowed up—the Hebrew arises renewed by the Holy Spirit, as he also crossed the Red Sea dry shod—where our fathers were baptized in the cloud and in the sea.”

“And Elijah said unto them, take the prophets of Baal,.... The four hundred and fifty that were upon the spot; for the number of the people of Israel, now gathered together, were equal to it; nor was it in Ahab's power to hinder it, and he might himself be so far surprised and convicted as not in the least to object to it: let not one of them escape: that there might be none of them left to seduce the people any more: and they took them; laid hold on them, everyone of them: and Elijah brought them down to the brook Kishon; which ran by the side, and at the bottom of Mount Carmel, into the sea; See Gill on Jdg 4:7, Jdg 5:21. and slew them there; intimating, that it was owing to the idolatry they led the people into that rain had been withheld, and the brooks were dried up, as this might be; or, as Ben Gersom thinks, that the land might not be defiled with their blood, but be carried down the river after it: these he slew not with his own hand, but by others he gave orders to do it; and this not as a private person, but as an extraordinary minister of God, to execute justice according to his law, Deu 13:1 by which law such false prophets were to die; and the rather he was raised up and spirited for this service, as the supreme magistrate was addicted to idolatry himself.”

“Then the fire of the Lord fell - It did not burst out from the altar; this might still, notwithstanding the water, have afforded some ground for suspicion that fire had been concealed, after the manner of the heathens, under the altar. Pindar's account of the Rhodians' settling is the isle of Rhodes, and their first sacrifice there, bears a near affinity to the account here given: the shower of gold descending on the sacrifice offered up without fire, to show the approbation of their god, is little more than a poetic account of the above transactions. Καιτοι γαρ αιθουσας εχοντες Σπερμ' ανεβαν φλογος ου Τευξαν δ' απυροις ἱεροις Αλσος εν ακροπολει· κεινοισι μεν ξαν - θαν αγαγων νεφελαι· Πολυν ὑσε χρυσον Pind. Olymp. Od. 7, ver. 86. The Rhodians, mindful of their sire's behest, Straight in the citadel an altar reared; But with imperfect rites the Power addressed, And without fire their sacrifice prepared; Yet Jove, approving, o'er the assembly spread A yellow cloud, that dropped with golden dews. West. Consumed the burnt-sacrifice - The process of this consumption is very remarkable, and all calculated to remove the possibility of a suspicion that there was any concealed fire. 1. The fire came down from heaven. 2. The pieces of the sacrifice were first consumed. 3. The wood next, to show that it was not even by means of the wood that the flesh was burned. 4. The twelve stones were also consumed, to show that it was no common fire, but one whose agency nothing could resist. 5. The dust, the earth of which the altar was constructed, was burned up. 6. The water that was in the trench was, by the action of this fire, entirely evaporated. 7. The action of this fire was in every case downward, contrary to the nature of all earthly and material fire. Nothing can be more simple and artless than this description, yet how amazingly full and satisfactory is the whole account!”

“Trench, as if it had been of an inflammable nature. Julian himself was forced to acknowledge this miracle. “This, says he, once happened under Moses, and, a long while after, again under Elias, the Thesbite.””
