Fill four barrels - This was done to prevent any kind of suspicion that there was fire concealed under the altar. An ancient writer under the name of Chrysostom, quoted by Calmet, says that he had seen under the altars of the heathens, holes dug in the earth with funnels proceeding from them, and communicating with openings on the tops of the altars. In the former the priests concealed fire, which, communicating through the funnels with the holes, set fire to the wood and consumed the sacrifice; and thus the simple people were led to believe that the sacrifice was consumed by a miraculous fire. Elijah showed that no such knavery could be practiced in the present case. Had there been a concealed fire under the altar, as in the case mentioned above, the water that was thrown on the altar must have extinguished it most effectually. This very precaution has for ever put this miracle beyond the reach of suspicion.
