Eliyahu relates to Ahav's personal fate and the terrible punishment to his dynasty in the aftermath of his sin toward Navot and his vineyard - the culmination of the sinful reign of Ahav. Surprisingly, Ahav rends his clothing, wears a sackcloth and fasts. It appears that God accepts Ahav’s repentance, as He marvels to Eliyahu, “Have you seen that Ahav has submitted before me?”
Was Ahav’s repentance sincere? Does God accept the repentance of a man who led such a sinful life?
