At the climax of the confrontation on Mount Carmel, Elijah acts in complete defiance of natural logic. While the false prophets attempted to ignite their sacrifice during the scorching midday heat, Elijah waits for the cooler evening hours and orders the altar to be drenched with water. He instructs the people to fill four pitchers of water and pour them over the burnt offering and the wood, repeating this process a second and then a third time.
The primary approach among commentators is that this intentional flooding was meant to magnify the impending miracle, proving beyond doubt that the fire that consumed the drenched sacrifice came directly from God. Furthermore, the water served to dispel any suspicions of trickery. Standard witchcraft is known to be neutralized by water, so drenching the site proved this was no mere illusion. However, because the highest forms of dark magic can withstand water, Elijah later engaged in deep prayer to ensure the people would not mistake the divine fire for an act of supreme sorcery [צוארי שלל].
Notably, Elijah initiated this dramatic display of pouring water on his own accord, driven by his absolute trust in God rather than a direct divine command. Because he took this bold step independently, he subsequently had to pray and plead for mercy, asking that God actually agree to send down the fire [רלב"ג, אברבנאל].
The specific numbers involved in this act carry profound symbolic weight. Pouring four pitchers three times results in twelve pitchers total, representing the unity of the twelve tribes of Israel, much like the twelve stones used to construct the altar [רד"ק, אברבנאל, אדרת אליהו]. The three distinct pourings correspond to the three Patriarchs: Abraham, Isaac, and Jacob [רד"ק]. Additionally, water serves as a symbol for the Torah. The three pourings allude to the three major sections of the Bible, while the four pitchers represent the four levels of biblical interpretation [אדרת אליהו].
On a mystical level, pouring the water was intended to draw down a flow of divine kindness to soften strict justice. The sequence of three pourings of four pitchers corresponds to three of God's names, each consisting of four letters [חומת אנך, צוארי שלל]. This action also aimed to repair the three lower spiritual worlds, each comprising four layers [אדרת אליהו], while simultaneously awakening the flow of rain from the highest realms down to the physical earth [מלבי"ם]. Beyond the symbolism, a miraculous event accompanied this very act. As Elisha poured the water over Elijah's hands, Elisha's fingers transformed into flowing springs, producing enough water to completely fill the surrounding trench [רש"י, רד"ק].
