(Luk 13:31) At that very hour some Pharisees came and said to him, “Get away from here, for Herod wants to kill you.”
(Luk 13:32) And he said to them, “Go and tell that fox, ‘Behold, I cast out demons and perform cures today and tomorrow, and the third day I finish my course.
(Luk 13:33) Nevertheless, I must go on my way today and tomorrow and the day following, for it cannot be that a prophet should perish away from Jerusalem.’
This is no fearful Jesus. He did not fear Herod. Nor did He fear for His own safety.
