Whom did Jesus call a fox?

31 At that very hour, some Pharisees came to Jesus and told Him, “Leave this place and get away, because Herod wants to kill You.” 32 But Jesus replied, “Go tell that fox, ‘Look, I will keep driving out demons and healing people today and tomorrow, and on the third day I will reach My goal.’ 33 Nevertheless, I must keep going today and tomorrow and the next day, for it is not admissible for a prophet to perish outside of Jerusalem. (Luke 13:32)
