Like the ancient prophet Elijah, who rebuked the wrongdoings of Ahab and Jezebel, John confronted Herod with the admonition: "It is not lawful for you to have your brother's wife." Herod's brother, Herod Philip, lived in Rome and was Herodias' legitimate husband. Driven by ambition, she abandoned him and married Herod Antipas, contravening the law which prohibited a man from marrying his brother's wife while the brother was still alive. This scheming woman sought to have John executed for denouncing her immoral actions, but her pleas only resulted in Herod arresting him instead. Although Herodias wanted John dead, Herod hesitated to carry out her murderous desires, fearing the backlash from the crowds who held John in high regard, knowing him to be a righteous and holy man. Thus, Herod valued his prisoner, obeying him in many matters and enjoying his company. This unusual regard for John allowed him some freedom within prison, enabling him to communicate with his disciples who informed him about the miracles of Christ, and he, in turn, sent them to Christ.
As the message of the Gospel spread, John the Baptist, who was imprisoned, ultimately faced a martyr's end. His denunciation of Herod's illicit relationship with Herodias ignited a fierce desire for vengeance within her. Fearing the loss of her status should Herod heed John's warnings and divorce her, she plotted to eliminate the voice of truth. Employing her cunning to manipulate Herod's already wavering resolve, she persuaded him, who respected and valued John's righteousness, to consider sacrificing John. However, out of concern for the people who honored John as a prophet, Herod postponed the execution, while Herodias continued to await a chance for revenge against John.
Herod Antipas had long been aware of the name and works of Christ through the widespread rumors that reached him (Matthew 14:1; Mark 6:14; Luke 9:7). Confounded, he inquired, "Who is this about whom I hear such things?" (Luke 9:9), suspecting that this miraculous figure might be the resurrected John the Baptist, whom he had slain (Matthew 14:2; Mark 6:14, 16). In his quest for certainty, he sought a chance to see Him (Luke 9:9).
