The answer is: Herod

Luke 13:31-32

In Luke 13:31-32, when Jesus refers to Herod as "that fox," He's really throwing out some sharp imagery. Calling someone a fox isn’t exactly a compliment; it denotes cunningness and deceit. Herod Antipas, the ruler of Galilee, was known for his manipulative behavior and politically shrewd nature. By characterizing him this way, Jesus highlights Herod's sly, treacherous ways when it comes to ruling and chasing down the truth.

The backdrop of this interaction is rich too. Some Pharisees warn Jesus that Herod wants to kill him, but instead of panicking, Jesus stands firm. He's on a mission, and no sly ruler is about to deter him! If anything, his confident response, essentially saying Herod can’t stop him, showcases the deeply rooted belief in a higher purpose that outstrips temporary political threats.

Fun fact: Herod's palace, known for its grandeur, that shimmered like a beautiful fortress amidst Judean hills, gives you a sense of the cultural backdrop of the time. Antipas is the same ruler who would later play a role in the trial of Jesus, underscoring the tension between governance and divine mandate throughout the New Testament.

So, when Jesus calls him a fox, it’s a powerful combination of humor, critique, and prophetic challenge in the face of impending danger. Plus, in biblical language, "fox" might remind some of the timeless contrasts between true wisdom and opulent folly!
