Despite Eliyahu's response to the events in the aftermath of the showdown on Mt. Carmel, the evidence of the next few chapters would seem to show that the prophets of Ba’al do not return. Instead, prophets of God - many of them false prophets - have a fixed presence in the royal court which attests to the success of Eiyahu. When Aram lays seige on Shomron, Ahav is prepared to be a vassal state, but refuses a complete capitulation. Whether it is national pride that drives Achav, according to the Pshat, or a religious pride in protecting the Sefer Torah, according to the Midrash, God comes to Ahav's aid and sends him the tools for a miraculous victory.
